Nonlinear KTP crystal Advantage:
KTP (KTiOPO4) is an excellent non-linear crystal. It exhibts high optical quality, broad transparent range, relatively effective SHG coefficient ( about 3 times higher than that of KDP), very high optical damage threshold, wide acceptance angle, small walk-off , and type Ⅰand type Ⅱ non-critial phase-matching (NCPM) in a wide wavelength range. KTP is the most commonly used material for frequency doubling of Nd:YAG laser and other Nd-doped lasers, particularly at the low or medium power density. The properties of KTP make it superior as an electro-optic modulator as well as an optical waveguide device, including phase modulators, amplitude modulators and directional couplers.
Nonlinear KTP crystal Applications:
• Second harmonic generator of radiation 1.064 µm
• Optical parametric oscilator in near IR region up to 4 µm
• Different frequency generator in near IR region
