Compact cavity of lasers.
High quality coating with Broad transparency range from 0.16 μm to 2.6 μm
Large Nonlinear Optical Coefficients
Wide Angular Bandwidth and Small Walk-off Angle
Broad Temperature and Spectral Bandwidth
High Electro-Optic Coefficient and Low Dielectric Constant
OPO (optical parametric oscillator)
OPO converts an input laser wave
(called “pump”) with frequency 
into two output waves of
lower frequency (
) by means
of second order nonlinear optical interaction.
The sum of the output waves’ frequencies is
equal to the input wave frequency: 
.
The two output waves are called “signal” and “idler”.
LASERTEC Provide compact OPO assemble for (LRF)laser range finder. Our KTP is widely used in both commercial and military lasers including R&D and medical systems, range-finders, lidar systems.
Applications:
Parametric Sources(OPG,OPA and OPO) for 0.6μm-4.5μm Tunable output.
