High-power, high-repetition UV beam generation with an all-solid-state laser

Borate Nonlinear Optical Crystals for Frequency Conversion

“…Katsura et al demonstrated high-power 213 nm generationby using the dried CLBO and 300 W 1064 nm beam [203]. The fundamental light source for frequency conversion was a Q-switched diode-pumped Nd:YAG master oscillator and power amplifier system.…”

35.1 W all-solid-state 355 nm ultraviolet laser

“…The most effective way to achieve such lasers is using the nonlinear optical (NLO) conversion of all-solidstate lasers operating in the near-infrared (NIR) 1.0 µm laser radiation. With the development of the borate NLO crystals, high-average-power DPSS UV lasers have been reported with these crystals, such as β-Ba [4], LiB 3 O 5 (LBO) [2,[5][6][7][8][9], CsB 3 O 5 (CBO) [10][11][12], CsLiB 6 O 10 (CLBO) [11,[13][14][15][16], BaAlBO 3 F 2 (BABF) [17], and so on. The NLO characteristics for 355 nm generation in borate crystals via type II sum-frequency mixing were listed in Table 1.…”

Highly efficient 355 nm UV generation with non-collinear phase-matching by a prism-coupled device based on CsLiB6O10

“…9) Since its development in the 1990s, CsLiB 6 O 10 (CLBO) has drawn significant attention due to its potential uses in high average power UV generation. [10][11][12] Nishioka et al reported 42 W output of 266 nm UV by CLBO, 11) while Katsura et al reported 10.2 W output of 213 nm UV achieved with SFG by CLBO. 12) Table I compares the THG properties of LBO and CLBO in Type I and Type II phase-matching.…”

The polarization directions for fundamental, second harmonic and third harmonic light are represented as expressions like "ooe", where "o" stands for ordinary light and "e" stands for extraordinary light.…”
