POLYUS
        Research & Development Institute
        is the largest laser center in Russia. The Institute was founded in
        1962. In 1999 POLYUS RDI received the status of Federal State Unitary
        Enterprise.
        The main lines of activities of the Institute are development and
        production of solid-state lasers and devices on their basis,
        semiconductor lasers of various types and transmitting-receiving modules
        for FOCs, laser gyros, laser medical and industrial systems, components
        of laser systems. Owing to the multistructure orientation, POLYUS RDI has
        retained its leading positions among high-tech enterprises during the
        market reforms in Russia. At present the Institute numbers more than
        1400 specialists including 800 engineers, technologists and scientists.
        Among them are 2 academicians, 17 doctors of sciences and more than 100
        candidates of sciences.
        In recent years the development work at the Institute has concentrated
        on creation of functionally complete devices and components having
        concrete users. The restructuring of the scientific staff proceeds in
        the same direction. As a consequence, the volume of orders in the
        internal market of Russia grows, and the export part is steadily half
        the volumes of orders of POLYUS RDI.
        The production
        base of POLYUS RDI provides all basic technologies necessary for
        development and manufacturing of products of quantum electronics. These
        are high-temperature Czochralski growth of active and nonlinear
        crystals, gaseous-phase epitaxy of semiconductor structures and future
        technologies for development of semiconductor laser chips, advanced
        technologies for deposition of thin-film antireflection and
        beam-splitting coatings, vacuum technologies. In recent years it has
        been possible to introduce also such new progressive processes as
        ion-beam deposition of mirrors and production of structures for
        high-brightness LEDs.
        The combination
        of high technologies available at POLYUS RDI the powerful scientific
        school for lasers and laser technologies, the experience of many years
        in scientific research and development work allow the Institute to be
        among the world leaders in this field.
        Today we offer for export more than 300 models of various types of
        lasers, devices and equipment for different applications on their basis.
        The POLYUS's products are manufactured at 5 Russian plants, and our
        possibilities go beyond the production presented in our Web-site. POLYUS
        RDI is able to offer a wide range of applied scientific research,
        development work and engineering services to the users.
        The development and production of devices based on solid-state and
        semiconductor lasers have been carried out at POLYUS RDI for more than
        two decades. A number of models of Nd:YAG laser rangefinders has been
        developed. The recently developed rangefinders use eye-safe lasers at
        1.54 mm. Based on pulsed semiconductor lasers, velocimeters/rangefinders
        providing an accuracy of several centimeters it a range up to 1 km have
        been developed and are produced serially.
        More than 50 models of pulsed solid-state lasers (with a pulse energy up
        to 1 J or a pulse repetition rate up to 400 Hz at an energy of 40 mJ)
        and CW solid-state lasers (with an output power up to 2 kW) are produced
        for such applications as metrology, location, industrial systems for
        welding, cutting, marking.
        Based on solid-state lasers, systems for manufacturing souvenirs (making
        a pattern in the bulk glass), laser medical systems for surgery,
        ophthalmology, cosmetology (laser epilators) have been developed. The
        main trends in the field of laser equipment are creation of compact
        multifunctional systems and development of new technologies. To develop
        solid-state lasers, the production of rods and nonlinear elements for
        solid-state lasers has been organized at POLYUS RDI.
        The production processes for growth, thermal treatment, optical
        treatment and deposition of dielectric and current-conducting coatings
        necessary for making modem laser rods, nonlinear elements electrooptic
        and passive Q-switches have been developed and introduced into
        production.
        As a result of combined research, the range of lasers has been broadened
        and their lasing performance has been improved. Besides Nd:YAG and
        Nd:YAP crystals, the production of Er, Ho, Tu, Cr:GSGG, ISGG, YAG and
        YAP, crystals operating within an eye-safe range of 1.5...2.1 mm has
        been organized. Of great interest are Cr4+ :YAG laser rods
        that allow tunable generation within 1.4... 1.6 mm. Another active
        material developed at POLYUS R&DI to produce tunable generation and
        mode-locked generation is Ti:sapphire.
        For diode-pumped solid-state lasers, microlaser elements have been
        developed that combine active and passive property (microchip lasers).
        New passive Q-switches based on transparent glassceramics doped with Co+2
        ions have been developed for eye-safe solid-state Er+3: glass
        laser at 1.5 mm.
        The KTP crystals developed at POLYUS RDI provide a frequency-doubling
        efficiency more than 50% and about the same slope efficiency in
        parametric generation.
        The photoreceiving devices being developed at POLYUS RDI are the most
        important part of the devices and systems where laser radiation serves
        as a main information carrier (rangefinders, locators, gyros,
        communication systems, etc.).
        One of the recent development works in this field was development of a
        highly sensitive photoreceiving device for the eye-safe rangefinder at
        l.54 mm. One of the leading lines in the POLYUS RDI activities is
        development and production of semiconductor lasers. More than 40 models
        of semiconductor lasers have been developed and are produced. In this
        area POLYUS RDI is also the leading scientific center in Russia. The use
        of quantum-well structures has allowed broadening of the spectral range
        of semiconductor lasers from 0.8 to 1.6 mm. A conventional feature of
        such diodes is a high degree of polarization of generated radiation. By
        now CW laser diodes up to 2W based on the quantum-well structures have
        been developed. The efficiency of such diodes is 35...40%. The pulsed
        laser diodes based on quantum-well structures provide an optical power
        of 20...23 W at a pulse width of 100...130 ns, a pulse repetition rate
        of 5...20 kHz and a pump current no more than 40A.
        Now POLYUS RDI completes the development of the domestic technology for
        manufacturing epitaxial wafers for high-brightness red and yellow LEDs
        and organizes their serial production. In this case the MOCVD technology
        is required, which is widely used at POLYUS RDI for production of a wide
        range of epitaxial structures for laser diodes including those based on
        AlInGaP.
        The third leading line in the development work at POLYUS RDI is laser
        gyroscopy for civil aviation. At present the accuracy of laser gyros
        lies in the range from 0.01°/h (the linearly polarized KM-11-1A with
        the resonator made of precision prisms using high-frequency excited
        discharge) to 1°/h (compact circularly polarized laser gyros with
        magnetooptic bias using dc-excited discharge).
        Laser gyros find application where their unique properties can be used
        most fully (the absence of moving mechanical parts, short readiness
        time, enhanced strength and resistance to mechanical and climatic
        action, higher potential accuracy and lower cost with comparable weight
        and overall dimensions).
        Today POLYUS RDI is one of the leading Russian enterprises in the field
        of laser medical equipment. Many Russian clinics are equipped with the
        systems for surgery and ophthalmology developed at POLYUS RDI. The
        further work is carried out in the directions of development of laser
        equipment and its introduction into cardiology and physiotherapy,
        urology, oncology, phthisiology, surgery (more compact equipment, new
        wavelengths), dermatology, ophthalmology (including equipment based on
        semiconductor lasers).
        The integrated use of the recent advances of the Institute in the field
        of laser engineering makes it possible to develop competitive high-tech
        laser medical equipment and to provide its wide introduction into
        medical practice.
        The high scientific and technological standard of POLYUS's products and
        active work in the field of external economic activity allows us to
        export our products, the results of investigations and development work,
        engineering services to various countries of Europe, Asia and America.
