Abstract	: An efficient diode-pumped, room temperature Ho:Tm:YLF disk amplifier was realized by end-pump configuration. Compared to side pump configuration, about a factor three improvement in system efficiency has been demonstrated. OCIS codes: (140.3280) Laser amplifiers; (140 3480) Lasers, diode-pumped Introduction Space based wind sensing coherent Doppler lidar requires an eye-safe, high energy, high efficiency and single frequency laser transmitter. Laser output energy ranging from 500 mJ to 2 J with an efficiency of 5% is required for an operational space coherent lidar 1 . We previously developed a high energy Ho:Tm:YLF master oscillator and side pumped power amplifier system 2 and demonstrated a 600-mJ single frequency pulse at a repetition rate of 10 Hz. The amplifier system consists of four side-pumped amplifiers, each having 7 J pump energy. Although the output energy is high, the optical-to-optical efficiency is only 2%. In particular, the optical-to-optical efficiency is ...
