A pulse transmission mode Q-switched Nd:YLF laser pumped by cylindrical microlens-collimated diode bars

摘要

A Q-switched cavity-dumped single-transverse-mode Nd:YLF laser pumped by two 60-W quasi-CW diode bars collimated using cylindrical microlens technology produced 4-mJ, 4.5-ns pulses. The pump geometry employed has many of the advantages of longitudinal pumping yet allows the use of high-power quasi-CW bars while requiring only 1 optical element.
