Even so, in order to process the crystal is extremely State-of-the-art production methods are required. For the reason that dawn of this crystal, focusing on this problem, we are now the one company on this planet that can be processed On this crystal.

According to the proof-of-theory experiment, the conversion performance of 23% implied the potential for reaching substantial-ability at the second Stokes wavelength on the Raman laser. If the pump laser of 1078 nm may very well be acquired at the standard power of 50 W, the output electric power of its 2nd Stokes wavelength at 1512 nm could possibly be greater than 10 W. The look of your Raman laser cavity should be optimized in order to steer clear of the problems of your M1 and diamond floor.
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。

LBO is also an outstanding nonlinear crystal which is usually applied to the SHG from the NIR for the inexperienced. The DUV laser is normally understood by two stages of SFG within the LBO crystals given that there is absolutely no section-matching angle for LBO to transform the green laser at 515 nm or 532 nm towards the DUV right by SHG [16]. Just lately, the NSBBF crystal has also demonstrated its opportunity to acquire a high conversion performance from 532 nm to 266 nm. The stroll-off angle and deff with the NSBBF are Practically much like These of CLBO [seventeen].
On one other aspect, the power scaling from the NIR laser is another element to increase the ordinary electric power in the 193-nm DUV laser. As a result of not enough the substantial-energy amplification Option in the NIR laser (such as at 1553 nm), nonlinear frequency processes for example optical parameter oscillation (OPO) might be placed on create a wavelength converter by shifting the wavelength from one μm to the desired wavelength and also acquiring relative bigger electrical power [21]. Recently, a diamond Raman laser showed its skill in reaching a significant power plus a large conversion performance with the 1st Stokes with the one-μm laser [22,23], which means the likelihood being utilized while in the 193-nm DUV laser era as a consequence of its substantial Raman achieve 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 2 times as huge as that of KDP. CLBO crystals may be developed within the stoichiometric melt with lower viscosity.
The event in the 193-nm laser was shown by stages of SFG. So as to scale the DUV laser energy correctly, a completely new idea on the 193-nm DUV laser technology is presented based upon the diamond Raman laser.
