Anti-Gray Tracking KTP Crystal
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°C
-
Mechanically stable
-
Low cost compare with BBO and LBO
Disadvantage:
-
Gray-tracking at high power limited it's application to moderate power density
Additional applications for KTP include mixed frequency, electro-optical modulation, optical parametric generation and optical waveguide.
Application:
-
Frequency Doubling (SHG) of Nd-doped Lasers for Green/Red Output
-
Frequency Mixing (SFM) of Nd Laser and Diode Laser for Blue Output
-
Parametric Sources (OPG, OPA and OPO) for 0.6mm-4.5mm Tunable Output
-
Electrical Optical(E-O) Modulators, Optical Switches, and Directional Couplers
-
Optical Waveguides for Integrated NLO and E-O Devices
