1-mJ/pulse Tm:YAG laser pumped by a 3-W diode laser.
Efficient 2-microm lasers are needed for many eye-safe laser radar applications. Pumping of a Tm:YAG crystal with the output from a 3-W diode laser has resulted in a cw output power of 0.5 W and Q-switched pulse energies in excess of 1 mJ/pulse at 100 Hz. Improved pump absorption with a near-circular pump beam could result in 2-mJ pulse energies.
