SOLID-STATE LASERS
POLYUS Research & Development Institute carries out a wide range of research and developments in the field of solid-state lasers for following main applications:
- industrial laser systems;
- medical laser systems;
- laser rangefinders;
- scientific research.
Our lasers are based on Nd:YAG and Nd:YAP crystals. The recent developments also use Cr, Nd:GSGG; Cr, Tm, Ho:YAG; Er:YAG; Ti:Saphire and Cr4+:YAG crystals. Output of CW Nd:YAG and Nd:YAP lasers achieves 1 kW in CW and pulse energy up to 3J in pulse operation IR range. Harmonic generators and OPO-converters are used to expand emitting range to UV and IR range.
