In comparison with BBO it capabilities bigger spectral and temperature acceptance, greater angle tolerance, in addition to a smaller walk-off angle. from 3289 $ shipping and delivery
We summarized The present advancement position on the superior-electricity DUV laser each in the wavelength of FHG of your 1-μm laser and at 193 nm. The the latest progress with the sound-point out/fiber laser, together with the nonlinear optical crystals, prompts not merely the common energy but will also the beam excellent (coherence) of the DUV lasers to an unprecedented amount.
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 equally the 1040 nm and 1078 nm laser come from 1 dual-wavelength Yb-doped fiber laser. Each laser is amplified by levels of fiber amplifier and Yb-doped resources amplifier, respectively.
On another facet, the facility scaling on the NIR laser is yet another part to improve the normal electric power on the 193-nm DUV laser. A result of the not enough the significant-electricity amplification Option from the NIR laser (such as at 1553 nm), nonlinear frequency processes such as optical parameter oscillation (OPO) can be applied to produce a wavelength converter by shifting the wavelength from one μm to the desired wavelength together with obtaining relative larger electric power [21]. Not long ago, a diamond Raman laser confirmed its capability in achieving a large electricity plus a higher conversion performance at the 1st Stokes in the 1-μm laser [22,23], which suggests the likelihood to generally be used within the 193-nm DUV laser technology due website to its large Raman achieve and huge frequency shift.

The heartbeat period of the next Stokes gentle was shortened to five ns as shown in Determine 7a, only one-shot picture with the oscilloscope, that is a typical phenomenon in Raman laser [forty four] while the pulse length with the pump laser was ten ns.
Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics on the Nd:YAG elementary laser wavelength. So that you can greatly enhance the injury threshold, small CLBO floor roughness, by extremely-precision machining, is required. Because the CLBO crystal has simple hydroscopic response and micro scratches in machining, ultra-precise machining of your CLBO crystal is often a hard technical trouble.
The beam profile shown in Figure 7b demonstrated a fantastic beam high quality as one of several deserves of Raman laser, which might be helpful to make a 193-nm DUV laser with a top quality beam.
Its UV absorption edge reaches a hundred and eighty nm. The productive nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as big as that of KDP. CLBO crystals is usually grown in the stoichiometric soften with reduced viscosity.
