Abstract :
A Tm laser pumped Mid-IR all solid-state laser is reported. A thulium laser is used to directly drive a ZnGeP2 optical parametric oscillator (OPO) with 1.99μm output to generate the 3~5μm wavelength. Diode pumped Tm:YAP laser operates on 1.99μm, repetition frequency of 10KHz, the optical to optical conversion efficiency is 28%. The all solid-state Mid-IR laser runs at room temperature and achieves over 1W at 3~5μm with an optical to optical conversion efficiency of 5.4% starting from the pump diode.
