Nonetheless, as a way to procedure the crystal is very Sophisticated producing strategies are required. For the reason that dawn of this crystal, engaged on this challenge, we are actually the only real corporation in the world which can be processed Within this crystal.
In comparison to BBO it options greater spectral and temperature acceptance, improved angle tolerance, and also a smaller sized stroll-off angle. from 3289 $ shipping
In accordance with the proof-of-principle experiment, the conversion effectiveness of 23% implied the opportunity of achieving large-electricity at the second Stokes wavelength on the Raman laser. If the pump laser of 1078 nm could be acquired at the standard energy of 50 W, the output electricity of its 2nd Stokes wavelength at 1512 nm may very well be in excess of ten W. The look of your Raman laser cavity need to be optimized so that you can stay away from the hurt from the M1 and diamond surface.
The average ability on the NIR laser nonetheless has the probable to become improved to tens of watts which include 70 W [26] In case the double-pass configuration might be used for your Yb:YAG SCF amplifier phase. That's why, if the conversion effectiveness of 31% from NIR to DUV might be however preserved at this greater power condition, the typical output power on the DUV laser at 258 nm might be over twenty W, which might be a extraordinary energy stage for that DUV laser and produce the unanticipated DUV laser machining results. Furthermore, for high-energy DUV laser, the UV harm from the nonlinear crystal, including the windows for CLBO crystal as well as the mirrors, is an additional important parameter for long-term and stable operation.

LBO can also be a wonderful nonlinear crystal which is always applied to the SHG through the NIR to the environmentally friendly. The DUV laser is generally recognized by two phases of SFG during the LBO crystals because there is absolutely no period-matching angle for LBO to convert the eco-friendly laser at 515 nm or 532 nm on the DUV specifically by SHG [sixteen]. Recently, the NSBBF crystal has also proven its potential to get a significant conversion performance from 532 nm to 266 nm. The wander-off angle and deff of your NSBBF are Pretty much comparable to Those people of CLBO [seventeen].

During the scientific and industrial programs, the beam top quality on the DUV laser is likewise a very important parameter. Notably, the beam good quality from the DUV laser radically influences the laser machining outcomes. The beam quality with the DUV laser is determined by that of the elemental laser as well as the crystal for the frequency conversion. A short while ago, a substantial-ability DUV laser (>10 W) at 258 nm was claimed using a beam high-quality of M2 < 1.5, which was produced by FHG of the Yb:YAG laser at 1030 nm utilizing the CLBO crystal [13]. This laser would bring on a much better laser machining consequence in comparison with the past DUV lasers with bigger M2.

The beam profile demonstrated in Determine 7b shown a very good beam good quality as one of the merits of Raman laser, which would be helpful to crank out a 193-nm DUV laser with a top quality beam.

The event in the 193-nm laser was shown by stages of SFG. So as to scale the DUV laser energy effectively, a whole new concept on the 193-nm DUV laser technology is presented based upon the diamond Raman laser.
