Even so, in an effort to process the crystal is rather advanced producing procedures are needed. Because the dawn of the crystal, working on this challenge, we at the moment are the sole corporation on this planet that may be processed Within this crystal.

In accordance with the evidence-of-basic principle experiment, the conversion efficiency of 23% implied the possibility of obtaining large-energy at the second Stokes wavelength with the Raman laser. If your pump laser of 1078 nm could be acquired at the common energy of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm could be much more than 10 W. The look from the Raman laser cavity must be optimized so as to avoid the problems from the M1 and diamond surface area.
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。

Both the 1040 nm and 1078 nm laser come from a single twin-wavelength Yb-doped fiber laser. Each individual laser is amplified by phases of fiber amplifier and Yb-doped components amplifier, respectively.
On the opposite aspect, the ability scaling in the NIR laser is an additional part to enhance the ordinary energy with the 193-nm DUV laser. Because of the insufficient the high-electrical power amplification Remedy on the NIR laser (by way of example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) can be applied to produce a wavelength converter by shifting the wavelength from one μm to the specified wavelength in addition to getting relative larger electrical power [21]. Lately, a diamond Raman laser showed its ability in achieving a higher energy and a superior conversion effectiveness for the 1st Stokes of the one-μm laser [22,23], which suggests the chance being utilized during the 193-nm DUV laser generation as a result of its higher Raman obtain and enormous frequency change.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the most effective non-linear crystal which generates ultraviolet harmonics from the Nd:YAG essential laser wavelength. So that you can boost the damage threshold, very low CLBO surface roughness, by extremely-precision machining, is needed. Since the CLBO crystal has easy hydroscopic reaction and micro scratches in machining, ultra-specific machining of the CLBO crystal is often a difficult technological difficulty.
