Attention! You can customise this product to your needs.
It exhibits high optical quality, broad transparent range, relatively high effective SHG coefficient (about 3 times higher than that of KDP), rather high optical damage threshold, wide acceptance angle, small walk-off and type I and type II non-critical phase-matching (NCPM) in a wide wavelength range.
KTP is the most commonly used material for frequency doubling of Nd:YAG lasers and other Nd-doped lasers, particularly at the low or medium power density.
We offer Positioning Mount 5APH59T-1 for Nonlinear Crystal Housing.
varna Efficient frequency conversion and Large non-linear optical coefficients
varna Wide transmission region from 350 nm to 4400 nm
varna Wide angular bandwidth and small walk-off angle
varna Broad temperature and spectral bandwidth
varna Low cost compare with BBO and LBO
