In comparison with BBO it options greater spectral and temperature acceptance, superior angle tolerance, along with a smaller sized stroll-off angle. from 3289 $ supply
According to the proof-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of achieving substantial-power at the second Stokes wavelength from the Raman laser. In the event the pump laser of 1078 nm may be received at the normal electric power of 50 W, the output electrical power of its 2nd Stokes wavelength at 1512 nm may very well be greater than ten W. The look of your Raman laser cavity should be optimized to be able to avoid the damage 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。

Due to the thermal lens influence while in the reliable-condition lasers, When the heating administration is insufficient, it is not quick to acquire the sound-condition laser with a high electrical power as well as a large beam top quality simultaneously. Just lately, with the event of the thin disk laser and single-crystal fiber (SCF) laser, a significant-energy laser at the fundamental wavelength (one μm) were realized with a great beam top quality In spite of a TEM00 manner beam [4,24], which would be good candidates for the basic with the DUV laser era. Yet another candidate for the fundamental is the superior-power fiber laser which could be obtained by coherent beam blend with M2 value fewer than 1.

The heartbeat period of the second Stokes mild was shortened to five ns as shown in Figure 7a, one-shot photograph from your oscilloscope, and that is a common phenomenon in Raman here laser [44] while the heartbeat length of the pump laser was ten ns.
What's more, combining the sound-condition laser with other nonlinear approach including stimulated Raman scattering, NIR lasers may be attained at new wavelengths with substantial energy and substantial beam high quality, which was tested from the evidence-of-basic principle experiment. This Raman laser plan presents a whole new route to the high-electrical power DUV laser, In particular in the wavelength of 193 nm.

The conversion effectiveness from essential NIR to DUV is from 5% to 36% based on the claimed leads to Desk one. Growing the conversion effectiveness will lessen the stress on the design and setup of the elemental laser amplifier plus the electric powered electrical power intake. A good beam good quality of the fundamental laser may even add to the escalating on the conversion performance and the appropriate electricity depth on the NIR and inexperienced laser from the SHG and FHG course of action, respectively. The best conversion efficiencies from NIR to inexperienced and inexperienced to DUV laser by use of CLBO crystal are 70% and about fifty%, respectively [twelve], which corresponds for the conversion efficiency of 35% from elementary to DUV.
