All-sound-state ultraviolet lasers have been extensively Employed in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of smaller quantity, long life, higher performance, very good beam good quality, extensive tuning and slim spectral line, etc. Utilizing large electricity near-infrared coherent mild resource as the basic frequency supply based on nonlinear tuning technological know-how, producing ultraviolet coherent radiation by multistage frequency conversion is viewed as an important strategy to create the ultraviolet coherent light-weight supply.

This cookie is accustomed to file the input contents as well as development on the input form. It does not retail outlet any personal details.

In accordance with the proof-of-theory experiment, the conversion performance of 23% implied the potential of acquiring large-electric power at the second Stokes wavelength of your Raman laser. In case the pump laser of 1078 nm might be attained at the typical electric power of 50 W, the output energy of its 2nd Stokes wavelength at 1512 nm could possibly be in excess of ten W. The look of your Raman laser cavity needs to be optimized so that you can steer clear of the destruction in the M1 and diamond surface.

The main element challenge of ultraviolet coherent light-weight resource mostly focuses on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is among the disorders for frequency transformation, so the growth, sizing, injury resistance, conversion performance and allowable parameter selection of nonlinear optical crystal are essential more and more.

LBO is usually a fantastic nonlinear crystal which is usually applied to the SHG through the NIR for the green. The DUV laser is generally understood by two levels of SFG from the LBO crystals since there is not any stage-matching angle for LBO to convert the green laser at 515 nm or 532 nm on the DUV directly by SHG [sixteen]. A short while ago, the NSBBF crystal has also proven its prospective to acquire a substantial conversion efficiency from 532 nm to 266 nm. The stroll-off angle and deff from the NSBBF are Pretty much much like those of CLBO [17].

On one other aspect, the facility scaling on the NIR laser is yet another part to boost the ordinary electrical power of the 193-nm DUV laser. Due to the not enough the superior-electric power amplification Remedy of the NIR laser (such as at 1553 nm), nonlinear frequency processes for example optical parameter oscillation (OPO) might be applied to make a wavelength converter by shifting the wavelength from one μm to the specified wavelength as well as obtaining relative greater electricity [21]. Not long ago, a diamond Raman laser confirmed its means in acquiring a significant electricity plus a significant conversion effectiveness on the 1st Stokes from the one-μm laser [22,23], which suggests the chance being applied inside the 193-nm DUV laser technology on account of its higher Raman get and enormous frequency shift.

Crylink is an open System, equally as our mission is to attach price, Crylink thinks that every man or woman and each business has one of a kind value, and we hope to attach with worthwhile you to deliver price and mirror price collectively.

Furthermore, combining the stable-point out laser with other nonlinear approach for instance stimulated Raman scattering, NIR lasers might be reached at new wavelengths with large ability and significant beam high-quality, which was examined via the evidence-of-theory experiment. This Raman laser plan presents a completely new path to the significant-energy DUV laser, In particular for the wavelength of 193 nm.

Tunable ultraviolet laser source according to sound-condition dye laser know-how and CsLiB6O10 harmonic technology

Its UV absorption edge reaches one hundred eighty nm. The successful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as significant as that of KDP. CLBO crystals is often developed within the stoichiometric soften with reduced viscosity.
