All-reliable-condition ultraviolet lasers are already extensively Utilized in the fields of mechanical flaw detection, lithography, micromachining and medicine for the benefits of modest quantity, extended lifestyle, significant effectiveness, fantastic beam high-quality, huge tuning and slender spectral line, etcetera. Making use of high electric power around-infrared coherent light-weight source as the basic frequency resource according to nonlinear tuning know-how, generating ultraviolet coherent radiation by multistage frequency conversion is viewed as a very important approach to establish the ultraviolet coherent light source.

LBO can be a wonderful nonlinear crystal which is always placed on the SHG from your NIR towards the environmentally friendly. The DUV laser is frequently recognized by two levels of SFG inside the LBO crystals since there's no phase-matching angle for LBO to convert the environmentally friendly laser at 515 nm or 532 nm towards the DUV directly by SHG [16]. A short while ago, the NSBBF crystal has also revealed its likely to obtain a substantial conversion effectiveness from 532 nm to 266 nm. The stroll-off angle and deff of the NSBBF are almost much like All those of CLBO [seventeen].

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics with the Nd:YAG essential laser wavelength. As a way to greatly enhance the injury threshold, low CLBO surface roughness, by extremely-precision machining, is necessary. As the CLBO crystal has easy hydroscopic response and micro scratches in machining, extremely-exact machining on the CLBO crystal is actually a tricky specialized trouble.
Tunable ultraviolet laser resource according to sound-point out dye laser technology and CsLiB6O10 harmonic generation
Its UV absorption edge reaches 180 nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as massive as that of KDP. CLBO crystals may be developed from the stoichiometric melt with reduce viscosity.
