18 Sep 2009 KTP has many favorable features that enable it to be widely used for frequency mixing for Red/Green/Blue output, and for OPO and OPA for visible to mid-infrared tunable output. NCPM KTP for OPO
The recently developed new application is the non-critical phase-matched (NCPM) KTP OPO/OPA application. The NCPM KTP OPO keeps the KTP crystal fixed in X-axis and tunes the pumping wavelength. If 1064nm pumping source, the output will be at 1.57mm (signal) and 3.3 mm (idler). Due to the favorable NLO properties of NCPM KTP, as high as 45% conversion efficiency was obtained with narrow output bandwidth and good beam quality. |
