| Nonlinear
optical (NLO) Crystals |
|
| The
nonlinear optical (NLO) crystals are mainly used in laser
frequency conversion application such as: SHG (Second Harmonic
Generation), THG (Third Harmonic Generation), OPO (Optical
parametric Generation), etc. |
|
| KTP
crystal |
| KTP
crystal is the most popular NLO crytal, especially in the
Nd laser frequency doubling (SHG 1064->532nm) applicaiton. |
