全固态紫外激光器以其体积小、寿命长、效率高、光束质量好、调谐范围宽、谱线窄等优点，广泛应用于机械探伤、光刻、微加工和医学等领域，等，利用大功率近红外相干光源作为基于非线性调谐技术的基频源，通过多级变频产生紫外相干辐射被认为是发展紫外相干光源的重要途径。紫外相干光源的关键问题是研制紫外波段的非线性光学变频晶体。非线性光学晶体是实现频率变换的条件之一，因此对非线性光学晶体的生长、尺寸、损伤电阻、转换效率和允许的参数范围提出了越来越高的要求。

As a result of thermal lens effect from the strong-state lasers, if the heating management is insufficient, It is far from straightforward to get the good-state laser using a significant power plus a superior beam high quality simultaneously. Just lately, with the event of the thin disk laser and single-crystal fiber (SCF) laser, a higher-power laser at the fundamental wavelength (1 μm) had been realized with an excellent beam good quality even with a TEM00 method beam [four,24], which would be very good candidates for the basic on the DUV laser era. An additional prospect for the basic would be the large-energy fiber laser which could be realized by coherent beam mixture with M2 benefit lower than one.
On another facet, the power scaling with the NIR laser is another component to raise the normal energy with the 193-nm DUV laser. As a result of not enough the large-ability amplification Resolution in the NIR laser (for instance at 1553 nm), nonlinear frequency procedures which include optical parameter oscillation (OPO) may be placed on establish a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength as well as getting relative higher energy [21]. Not too long ago, a diamond Raman laser showed its capacity in attaining a substantial electricity in addition to a superior conversion performance with the 1st Stokes in the 1-μm laser [22,23], which means the likelihood to become applied inside the 193-nm DUV laser generation because of its superior Raman get and huge frequency shift.

Its UV absorption edge reaches 180 nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as big as that of KDP. CLBO read more crystals is usually grown within the stoichiometric melt with lessen viscosity.
The development on the 193-nm laser was shown by stages of SFG. In an effort to scale the DUV laser ability efficiently, a different concept in the 193-nm DUV laser technology is presented based upon the diamond Raman laser.
