KTP Kristal

Potassium Titanium Oxide Phosphate (KTiOPO4 ), or KTP, is an efficient nonlinear optical crystal in the visible to infrared spectral region with relatively low cost. It has large nonlinear coefficient. The effective nonlinear optical coefficient of KTP deff at 1064nm is more than 1.5 times that of BBO. It's damage threshold is near 1 GW/cm2 for 1 Hz 10 ns pulses at 1064nm. However, it is now limited to moderate to low power applications due to it's gray-tracking problem. Recently we have developed gray-tracking-improved KTP (I-KTP) which has significantly raised the gray-tracking trigger power.

Advantage:

Efficient frequency conversion(1064nm SHG conversion efficiency is about 80%)

Large nonlinear optical coefficients(15 times that of KDP)

Wide angular bandwidth and small walk-off angle

Broad temperature and spectral bandwidth

High thermal conductivity (2 times that of BNN crystal )

Moisture free

Minimum mismatch gradient

Super-polished optical surface

No decomposition below 900

Mechanically stable

Low cost compare with BBO and LBO
