When compared to BBO it attributes much larger spectral and temperature acceptance, improved angle tolerance, and a more compact wander-off angle. from 3289 $ delivery
We summarized The present improvement standing from the higher-energy DUV laser the two on the wavelength of FHG of your 1-μm laser and at 193 nm. The latest enhancement from the stable-point out/fiber laser, along with the nonlinear optical crystals, prompts not just the common electricity but in addition the beam good quality (coherence) with 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。
On the other hand, the beam excellent of this increased power DUV laser would turn into even worse because of more significant thermal and nonlinear consequences. Consequently, the frequency conversion procedures ought to be thoroughly designed to mitigate the aforementioned results. Consequently, a high-electricity DUV laser for the FHG of one μm with a fantastic beam top quality could be attained and may be valuable for acquiring the shorter wavelength DUV lasers for example 193 nm by SFG.
LBO is also a superb nonlinear crystal which is often placed on the SHG from your NIR on the inexperienced. The DUV laser is often realized by two levels of SFG in the LBO crystals given that there is not any section-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm on the DUV specifically by SHG [sixteen]. Recently, the NSBBF crystal has also shown its possible to obtain a large conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff from the NSBBF are Virtually comparable to Those people of CLBO [seventeen].
On another click here side, the power scaling of the NIR laser is yet another component to enhance the normal power of the 193-nm DUV laser. Because of the insufficient the high-ability amplification Alternative in the NIR laser (for example at 1553 nm), nonlinear frequency processes such as optical parameter oscillation (OPO) may be placed on create a wavelength converter by shifting the wavelength from one μm to the specified wavelength in addition to getting relative higher electrical power [21]. Recently, a diamond Raman laser showed its potential in acquiring a large ability along with a substantial conversion performance at the 1st Stokes from the 1-μm laser [22,23], which suggests the likelihood to be applied from the 193-nm DUV laser generation as a result of its large Raman obtain and large frequency change.

The development on the 193-nm laser was shown by stages of SFG. So as to scale the DUV laser energy proficiently, a brand new principle in the 193-nm DUV laser era is introduced according to the diamond Raman laser.
