“…To date, the shortest wavelengths generated via quadratic phase-matched interactions are reported in LBO (172.7 nm) [36], CsLiB 6 O 10 (175 nm) [37], KB 5 O 8 ·4H 2 O (166 nm) [38] crystals. Typical generated pulse energy ranges from tens to hundreds of nanojoules in the femtosecond regime.…”

We report on efficient generation of the ultrashort ultraviolet light pulses by means of phase-matched four-wave optical parametric amplification and four-wave difference frequency mixing in UV-transparent solids with cubic nonlinearity. Broadband four-wave optical parametric amplification around 330 nm is investigated theoretically and demonstrated experimentally in optically isotropic materials, such as fused silica and CaF2 crystals. The results suggest that powerful broadband ultraviolet pulses as short as 7.5 fs (in the transform limit) could be amplified in the field of milijoule 1-ps visible pulses. Efficient generation of 1-ps pulses at the 3rd (351 nm), 5th (211 nm), and, in particular, 6th (176 nm) harmonics of the Nd:glass laser is experimentally demonstrated through non-collinearly phase-matched four-wave difference-frequency mixing in fused silica, CaF2 and MgF2 crystals.

“…The BABO crystal LBO was used to generate the DUV in the range of 172.7-187 nm by phase-matched sum-frequency mixing of the Ti:sapphire's (1kHz 0.3mJ, 740-850 nm, 150-200fs) fourth harmonic (ω+3ω) and a parametrically generated infrared pulse which was generate by an optical parametric generator/amplifier scheme with the same Ti:sapphire laser as the pump source. 4) A similar experimental setup as LBO was used to generate the DUV from 172 down to 166nm in a KB5 crystal. 5) In addition, the KB5 was the first borate crystal to achieve 194-nm coherent light output with the sum-frequency mixing method (792nm+515nm→194nm).…”

General review for the progress on all solid state deep ultraviolet (DUV) laser with a KBe 2 BO 3 F 2 (KBBF) crystal was given in the paper. The frequency-conversion characteristics of KBBF crystal and the comparison between this crystal and other borate nonlinear optical crystals were simply described. A special prism coupling technique (PCT) for DUV laser generation and some excellent experimental results from the application of this crystal were commented. At last, we believe that the output power and conversion efficiency could be greatly increased in the future if the thicker KBBF crystal with good optical quality is grown and the application technique of solid state DUV laser is further developed.

“…Great efforts have been made to extend the spectral range using nonlinear processes [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Optical parametric amplifier (OPA) and optical parametric oscillator (OPO) technologies are among the most successful methods for generating µJ-level pulses with spectral ranges from UV to mid-IR [32][33][34][35].…”

This paper introduces and discusses the main aspects of multicolored femtosecond pulse generation using cascaded four-wave mixing (CFWM) in transparent bulk materials. Theoretical analysis and semi-quantitative calculations, based on the phase-matching condition of the four-wave mixing process, explain the phenomena well. Experimental studies, based on our experiments, have shown the main characteristics of the multicolored pulses, namely, broadband spectra with wide tunability, high stability, short pulse duration and relatively high pulse energy. Two-dimensional multicolored array generation in various materials are also introduced and discussed.
