All-solid-state ultraviolet 330 nm laser from frequency-doubling of Nd:YLF red laser in CsB 3 O 5

Generation of femtosecond laser pulses at 396 nm in K 3 B 6 O 10 Cl crystal

“…In 2015, using BBSAG crystals, high repetition, tunable deep-ultraviolet pulse below 200 nm was obtained by Meng et al [11] Chen et al demonstrated a UV 330-nm laser in CBO crystal through SHG of Nd:YLF red laser in 2016. [12] In the same year, 266-nm UV light generated with BABF crystal was presented by Yang et al [13] Recently, Wu et al reported on K 3 B 6 O 10 Cl (KBOC) as a novel high quality NLO crystal with a size of up to 35 mm × 35 mm × 11 mm. [14] Its novel physical and optical properties exhibit a great potential for nonlinear frequency conversion in the UV spectral range.…”

A compact continuous-wave intracavity frequency doubling Pr:YLF ultraviolet laser at 360 nm

“…UV laser has lots of advantages such as short wavelength, easy focusing, high resolution, and large energy, can be widely used in many elds, including spectroscopy, biological analysis, medicine, precision manufacturing, optical data storage, high-resolution printing and lithography [1][2][3][4][5][6]. There are several approaches to obtain UV lasers, the most broadly applied methods is to use nonlinear crystal frequency tripling Nd 3+ :YAG lasers in the cavity.…”
