Product description

Parameters

Introduction to KTP: It has the characteristics of large non-linear coefficient, large allowable temperature and allowable angle, high laser damage threshold, stable chemical properties, non-deliquescent, moderate mechanical strength, frequency doubling conversion efficiency up to 70% or more. It is a medium and small power solid The best frequency doubling material for green lasers.

Application scope:

Now the main applications are double frequency and OPO applications (laser ranging), especially OPO applications have developed rapidly in recent years. Neodymium-doped crystal laser double frequency (SHG) obtains green/red light output Solid-state laser mixing (SFM) such as neodymium-doped crystal to obtain blue light output OPG, OPA and OPO get dimmable in the range of 0.6um-4.5um Electro-optical (E-O) modulation, optical switch Optical waveguide, making periodically polarized KTP devices Mainly used in industrial processing (internal carving, marking, etc.), military distance measurement, blinding weapons, laser medical treatment (beauty), laser demonstration and scientific research experiments.
