5 Essential Elements For CLBO Crystal

Blog Article

Within this paper, the new lapping slurry and sprucing slurry are introduced. Plus the deliquescence diploma of CLBO is fallen to lowest. A fresh working technological innovation is likewise adopted. After tough polishing, the focus of extremely-precision polishing slurry is elevated correctly. So does the ultra-precision polishing speed, along with the wiping speed is faster when compared to the deliquescence speed. The CLBO crystal area roughness can accomplish 1nm and continue to keep the surface quality very well. Obtain through your establishment

We summarized The existing progress standing on the higher-power DUV laser both of those at the wavelength of FHG with the 1-μm laser and at 193 nm. The the latest growth of the reliable-point out/fiber laser, plus the nonlinear optical crystals, prompts not merely the typical energy but additionally the beam good quality (coherence) from the DUV lasers to an unparalleled level.

For illustration, The present concave OC could be replaced by a plane mirror which could mitigate the facility density about the surface of M1 and the diamond. Also, employing higher destruction threshold coatings for M1 and diamond would also Enhance the output power with no damages. Then, the NIR laser in the 2nd Stokes wavelength could be substantial sufficient, and its fantastic beam high quality, to crank out the ultimate DUV laser at 193 nm using a significant average electrical power.

LBO is also a fantastic nonlinear crystal which is always applied to the SHG within the NIR on the eco-friendly. The DUV laser is often understood by two levels of SFG in the LBO crystals considering that there is not any section-matching angle for LBO to transform the environmentally friendly laser at 515 nm or 532 nm into the DUV directly by SHG [sixteen]. Recently, the NSBBF crystal has also shown its possible to get a substantial conversion effectiveness from 532 nm to 266 nm. The walk-off angle and deff of the NSBBF are almost comparable to All those of CLBO [17].

Tunable ultraviolet laser resource based upon good-point out dye laser technological know-how and CsLiB6O10 harmonic technology

The conversion effectiveness from fundamental NIR to DUV is from five% to 36% according to the documented results more info in Table one. Growing the conversion performance will reduce the load on the look and setup of the basic laser amplifier as well as the electrical ability consumption. A superb beam high-quality of the fundamental laser will even lead into the increasing in the conversion effectiveness together with the right ability depth of your NIR and environmentally friendly laser during the SHG and FHG system, respectively. The best conversion efficiencies from NIR to environmentally friendly and inexperienced to DUV laser by utilization of CLBO crystal are 70% and around 50%, respectively [12], which corresponds towards the conversion efficiency of 35% from essential to DUV.
