As the development of high-power diode-pumped solid state laser (DPSSL), thermal effects in the solid state laser media have become a bottleneck of the laser development Therefore, attempts to develop diode-pumped gas laser are conducted, to achieve more efficient thermal management Laser diode-pumped alkali laser ( DPAL ), a new high -power laser, combines some advantages such as high power, efficient diode -pumping, good thermal management and optical properties in gas media, and high quantum efficiency (-99%) for D transition of the alkali metal atoms. It is expected to realize high-average-power laser with good beam quality (near-diffraction-limited) and high efficiency (slope efficiency>80%), which can find a lot of applications in power beaming, military, drilling oil and gas wells and laser material processing. The principle, technology, new development and applications of DPAL are described.
