2.55 W continuous-wave 378 nm laser by intracavity frequency doublingof a diode-pumped Alexandrite laser
2021
A high-power continuous-wave (CW) ultraviolet (UV) laser at 378 nm
from an intracavity frequency-doubled Alexandrite laser has been
demonstrated with 638 nm fiber-coupled laser diodes as the pump source. A
maximum output power of 2.55 W was obtained, which is the highest power
for CW frequency-doubled Alexandrite lasers, to the best of our knowledge,
corresponding to the optical-to-optical conversion efficiency of 7.9% from
638 nm pump laser to 378 nm UV laser. The beam quality factors
M2 were measured to be 2.19 and 2.47 in x and
y directions at UV output power of 1 W, respectively.
