CLaser develop GTR-KTP crystal to replace of KTP. GTR-KTP has the following advantage compare with the KTP crystal:
High damage threshold
Without gary-track in high power cw intracavity application.
Lower absorption in 532nm
Higher resistivity
Frequency doubling (SHG) of Nd-doped lasers for green/red outputs.
Frequency mixing (SFM) of Nd laser and diode laser for blue outputs.
Parametric sources (OPG, OPA and OPO) for 600nm-4500nm tunable outputs.
E-O modulators, optical switches, directional couplers.
