Nonetheless, to be able to process the crystal is incredibly Innovative production tactics are necessary. Since the dawn of the crystal, working on this obstacle, we are actually the only corporation on the planet that can be processed In this particular crystal.

According to the proof-of-theory experiment, the conversion efficiency of 23% implied the potential for reaching substantial-electricity at the 2nd Stokes wavelength with the Raman laser. If the pump laser of 1078 nm might be obtained at the typical energy of fifty W, the output power of its 2nd Stokes wavelength at 1512 nm may be in excess of 10 W. The design from the Raman laser cavity ought to be optimized as a way to stay away from the damage from the M1 and diamond surface.
For example, the current concave OC could get replaced by a plane mirror which could mitigate the facility density on the area of M1 as well as diamond. Also, utilizing large injury threshold coatings for M1 and diamond would also improve the output ability with no damages. Then, the NIR laser in the 2nd Stokes wavelength could be higher sufficient, along with its superior beam top quality, to deliver the ultimate DUV laser at 193 nm using a significant common electrical power.

LBO is likewise a superb nonlinear crystal which is often applied to the SHG with the NIR towards the inexperienced. The DUV laser is generally recognized website by two phases of SFG in the LBO crystals considering that there is no phase-matching angle for LBO to transform the green laser at 515 nm or 532 nm for the DUV right by SHG [16]. Just lately, the NSBBF crystal has also demonstrated its likely to get a large conversion efficiency from 532 nm to 266 nm. The walk-off angle and deff of your NSBBF are Pretty much much like Individuals of CLBO [17].

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the simplest non-linear crystal which generates ultraviolet harmonics with the Nd:YAG elementary laser wavelength. As a way to increase the hurt threshold, lower CLBO surface area roughness, by ultra-precision machining, is needed. Since the CLBO crystal has effortless hydroscopic reaction and micro scratches in machining, ultra-specific machining on the CLBO crystal is often a tricky specialized issue.
Tunable ultraviolet laser supply according to stable-point out dye laser engineering and CsLiB6O10 harmonic technology
The conversion efficiency from elementary NIR to DUV is from 5% to 36% based on the reported ends in Desk 1. Escalating the conversion performance will reduce the burden on the look and set up of the elemental laser amplifier in addition to the electric powered power usage. A superb beam high-quality of the fundamental laser will even lead on the rising on the conversion performance together with the appropriate ability intensity on the NIR and green laser during the SHG and FHG course of action, respectively. The highest conversion efficiencies from NIR to environmentally friendly and inexperienced to DUV laser by use of CLBO crystal are 70% and around fifty%, respectively [12], which corresponds into the conversion performance of 35% from basic to DUV.
