Product Description

Potassium Titanyl Phosphate (KTiOPO4 or KTP) is an excellent Nonlinear optical crystal, widely used in both commercial and military lasers. However conventional KTP suffer a significant drawbacks.

The gray track phenomena in conventional KTP limit its application in high repetition and high power laser system. The occurrence of gray-track can be measured by an increase of bulk absorption by a strong CW 532nm green laser within several minutes. This measurement can be performed with Photo-thermal Common-path interferometer.

As Nonlinear Optical Crystals, coupletech will provide products as customers specifications. And also provide other nonlinear optical materials, such as :KTP Crystals, BBO Crystals, LBO Crystals, BIBO Crystals, KTA Crystals and LN Crystals.

GTR-KTP NLO Crystal TestGray Tracking Test:

When a green laser beam (400mW, beam diameter 0.07mm, power density 10KW/cm2) goes through the crystal, it causes an increase in the IR absorption of the crystal. This phenomenon is correlated with gray tracking effect. The following graphs show the different absorption levels at 1064nm between Coupletech's GTR KTP and the conventional KTP.
