Nevertheless, so that you can method the crystal is quite Innovative manufacturing procedures are demanded. Since the dawn of the crystal, working on this problem, we are now the only company in the world which can be processed With this crystal.

Based on the evidence-of-theory experiment, the conversion effectiveness of 23% implied the potential of accomplishing significant-ability at the 2nd Stokes wavelength with the Raman laser. If the pump laser of 1078 nm can be obtained at the typical electrical power of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm may be more than 10 W. The design of the Raman laser cavity really should be optimized as a way to avoid the injury of the 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。

As a result of thermal lens effect from the sound-state lasers, Should the heating management is inadequate, it is not simple to obtain the strong-state laser with a large electrical power as well as a significant beam high-quality simultaneously. Lately, with the event of the thin disk laser and solitary-crystal fiber (SCF) laser, a substantial-electrical power laser at the elemental wavelength (one μm) were recognized with a superb beam high-quality even with a TEM00 mode beam [4,24], which would be very good candidates for the basic in the DUV laser technology. Another prospect for the basic will be the higher-power fiber laser which might be reached by coherent beam blend with M2 worth under one.

In the scientific and industrial programs, the beam good quality of the DUV laser is additionally a vital parameter. Significantly, the beam high-quality in the DUV laser drastically has an effect on the laser machining success. The beam high-quality on the DUV laser is set by that of the fundamental laser as well as crystal for the frequency conversion. Recently, a large-energy DUV laser (>ten W) at 258 nm was noted by using a beam high quality of M2 < one.five, which was created by FHG of a Yb:YAG laser at 1030 nm using the CLBO crystal [thirteen]. This laser would bring about a far better laser machining outcome as compared to the prior DUV lasers with much larger M2.
The pulse period of the next Stokes gentle was shortened to five ns as shown in Figure 7a, an individual-shot photograph from your oscilloscope, that's a common phenomenon in Raman laser [44] while the heartbeat duration with the pump laser was 10 ns.
Additionally, combining the good-state laser with other nonlinear procedure for instance stimulated Raman scattering, NIR lasers can be reached at new wavelengths with superior electrical power and high beam excellent, which was analyzed through the evidence-of-basic principle experiment. This Raman laser plan provides a completely new route to the large-ability DUV laser, In particular at the wavelength of 193 nm.

Its UV absorption edge reaches one hundred eighty nm. The productive nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as big as that of KDP. CLBO crystals is usually grown within the stoichiometric soften with decreased viscosity.
