All-sound-state ultraviolet lasers are already broadly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medicine for some great benefits of compact quantity, extended lifetime, superior performance, very good beam good quality, vast tuning and narrow spectral line, etcetera. Making use of large electric power around-infrared coherent light supply as the elemental frequency source based on nonlinear tuning technology, generating ultraviolet coherent radiation by multistage frequency conversion is considered to be a significant strategy to build the ultraviolet coherent light supply.

LBO is usually a fantastic nonlinear crystal which is usually placed on the SHG through the NIR into the eco-friendly. The DUV laser is normally recognized by two stages of SFG inside the LBO crystals considering the fact that there's no period-matching angle for LBO to transform the green laser at 515 nm or 532 nm for the DUV specifically by SHG [sixteen]. A short while ago, the NSBBF crystal has also revealed its opportunity to get a substantial conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff with the NSBBF are Just about just like These of CLBO [17].

Additionally, combining the good-point out laser with other nonlinear system like stimulated Raman scattering, NIR lasers could possibly be obtained at new wavelengths with higher electricity and significant beam high-quality, which was analyzed by the evidence-of-basic principle experiment. This Raman laser plan presents a new path to the superior-ability DUV laser, especially for the wavelength of 193 nm.
