Rumored Buzz on CLBO Crystal

On this paper, The brand new lapping slurry and sprucing slurry are introduced. Along with the deliquescence diploma of CLBO is fallen to least expensive. A new Functioning technologies can be adopted. Immediately after tough sprucing, the focus of ultra-precision sprucing slurry is increased thoroughly. So does the extremely-precision sprucing velocity, as well as wiping pace is quicker compared to the deliquescence pace. The CLBO crystal surface roughness can attain 1nm and maintain the floor high-quality properly. Accessibility via your institution

According to the proof-of-principle experiment, the conversion effectiveness of 23% implied the potential for reaching large-electricity at the second Stokes wavelength in the Raman laser. In case the pump laser of 1078 nm may very well be attained at the standard ability of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm may very well be greater than 10 W. The design in the Raman laser cavity must be optimized in an effort to avoid the damage with the M1 and diamond surface area.
For illustration, the current concave OC could get replaced by a plane mirror which could mitigate the facility density on the floor of M1 as well as diamond. In addition, applying large problems threshold coatings for M1 and diamond would also improve the output electrical power with no damages. Then, the NIR laser within the 2nd Stokes wavelength might be higher more than enough, along with its great beam top quality, to make the final DUV laser at 193 nm by using a substantial regular electric power.

On the opposite facet, the power scaling with the NIR laser is another part to increase the common energy from the 193-nm DUV laser. A result of the lack of the higher-energy amplification Remedy of your NIR laser (as an example at 1553 nm), nonlinear frequency processes like optical parameter oscillation (OPO) could possibly be applied to create a wavelength converter by shifting the wavelength from one μm to the specified wavelength together with getting relative increased electricity [21]. A short while ago, a diamond Raman laser showed its skill in acquiring a higher electric power as well as a substantial conversion effectiveness for the 1st Stokes with the 1-μm laser [22,23], which implies the chance being utilized inside the 193-nm DUV laser generation thanks to its significant Raman obtain and large frequency change.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics in the Nd:YAG basic laser wavelength. As a way to improve the harm threshold, low CLBO area roughness, by extremely-precision machining, is needed. As the CLBO crystal has uncomplicated hydroscopic reaction and micro scratches in machining, extremely-exact machining from the CLBO crystal is a complicated specialized dilemma.
