The DS series UV diode-pumped solid-state Q-switched lasers from Photonics Industries International Inc. offer a range of pulse energies, repetition rates and widths. They provide an M2 <1.1 beam mode quality and up to a 20-W TEM00 profile. The lasers are available with a choice of Nd:YLF, Nd:YAG and Nd:YVO4 platforms. The typical output has pulse-to-pulse instability of <1% rms. The devices are suitable for applications that require high pulse energy at low repetition rates.
