All-sound-state ultraviolet lasers have already been broadly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of tiny volume, prolonged lifestyle, large effectiveness, superior beam quality, wide tuning and narrow spectral line, etcetera. Employing significant ability in close proximity to-infrared coherent mild resource as the basic frequency resource based upon nonlinear tuning technological innovation, producing ultraviolet coherent radiation by multistage frequency conversion is considered to be a vital way to produce the ultraviolet coherent light-weight supply.

As compared to BBO it capabilities larger spectral and temperature acceptance, far better angle tolerance, and also a smaller walk-off angle. from 3289 $ supply

Based on the proof-of-theory experiment, the conversion performance of 23% implied the potential of obtaining high-electricity at the 2nd Stokes wavelength of the Raman laser. In case the pump laser of 1078 nm could be obtained at the average electrical power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm could possibly be over 10 W. The look with the Raman laser cavity need to be optimized so that you can steer clear of the hurt in 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。

Alternatively, the beam quality of this better electrical power DUV laser would develop into even worse as a result of a lot more major thermal and nonlinear results. Hence, the frequency conversion procedures needs to be diligently made to mitigate the aforementioned outcomes. Consequently, a high-electrical power DUV laser for the FHG of one μm with a superb beam excellent may very well be attained and may be beneficial for obtaining the shorter wavelength DUV lasers such as 193 nm by SFG.

LBO is usually a superb nonlinear crystal which is often placed on the SHG in the NIR on the environmentally friendly. The DUV laser is normally recognized by two phases of SFG during the LBO crystals because there is absolutely no period-matching angle for LBO to transform the inexperienced laser at 515 nm or 532 nm to your DUV specifically by SHG [16]. Not too long ago, the NSBBF crystal has also demonstrated its opportunity to acquire a high conversion efficiency from 532 nm to 266 nm. The wander-off angle and deff of the NSBBF are almost similar to Those people of CLBO [seventeen].

On one other facet, the facility scaling of your NIR laser is another factor to improve the common energy of the 193-nm DUV laser. Because of the not enough the significant-electrical power amplification Answer of your NIR laser (one example is at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could possibly be placed on establish a wavelength converter by shifting the wavelength from one μm to the specified wavelength and also getting relative greater electric power [21]. Recently, a diamond Raman laser showed its potential in acquiring a high electrical power and also a superior conversion performance at the 1st Stokes of the one-μm laser [22,23], which implies the possibility for being utilized from the 193-nm DUV laser technology because of its higher Raman acquire and large frequency shift.

The conversion performance from basic NIR to DUV is from five% to 36% according to the documented ends in Desk 1. Rising the conversion performance will reduce the burden on the design and set up of the fundamental laser amplifier together with the electric energy intake. A very good beam high quality of the basic laser may even lead to your expanding of the conversion efficiency in addition to the appropriate energy intensity of the NIR and green laser in the SHG and FHG process, respectively. The best conversion efficiencies from NIR to inexperienced and eco-friendly to DUV laser by usage of CLBO crystal are 70% and all over 50%, respectively [12], more info which corresponds into the conversion effectiveness of 35% from fundamental to DUV.
