Paper Abstract

A maximum output power of 18.6 W has been measured at a pump power of 23.7 W in a Tm:fiber laser pumped adhesive-free bonded (AFB®) YAG/Ho:YAG/YAG composite. The corresponding optical-to-optical efficiency and slope efficiency are 78.5% and 81.2%, respectively. When the laser is operated in Q-switched mode, the shortest laser pulse width of 11 ns has been measured in our experiment at repetition rate of 5 KHz. The laser has been used as pump source of a mid-infrared ZGP OPO. The wavelength tuning range from 3.06 to 6.6 μm has been achieved in a 15-mm long ZGP crystal. The maximum output power is 1.44 W at pump power of 10 W with repetition rate of 5 KHz.
