Ultra-low threshold CW Triply Resonant OPO in the near infrared using Periodically Poled Lithium Niobate
Abstract
We have operated a CW triply resonant OPO using a PPLN crystal pumped by a Nd:YAG laser at 1.06 micron and generating signal and idler modes in the 2-2.3 micron range. The OPO was operated stably in single mode operation over large periods of time with a pump threshold as low as 500 microwatts.
