All-stable-point out ultraviolet lasers have already been greatly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of tiny volume, extended daily life, large efficiency, good beam quality, wide tuning and slender spectral line, and so on. Employing superior electrical power close to-infrared coherent light resource as the basic frequency supply based upon nonlinear tuning technologies, making ultraviolet coherent radiation by multistage frequency conversion is thought to be a very important way to acquire the ultraviolet coherent light source.

We summarized The present enhancement position in the superior-power DUV laser both of those for the wavelength of FHG of the 1-μm laser and at 193 nm. The recent progress from the solid-condition/fiber laser, together with the nonlinear optical crystals, prompts don't just the normal energy and also the beam quality (coherence) in the DUV lasers to an unprecedented stage.
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 originate from just one twin-wavelength Yb-doped fiber laser. Each individual laser is amplified by phases of fiber amplifier and Yb-doped resources amplifier, respectively.

The heartbeat period of the next Stokes light was shortened click here to 5 ns as revealed in Figure 7a, an individual-shot photograph from the oscilloscope, which happens to be a typical phenomenon in Raman laser [forty four] whilst the heart beat length of your pump laser was 10 ns.

Its UV absorption edge reaches 180 nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as huge as that of KDP. CLBO crystals might be grown within the stoichiometric melt with lower viscosity.
