When compared with BBO it features greater spectral and temperature acceptance, superior angle tolerance, along with a lesser walk-off angle. from 3289 $ delivery
We summarized The present advancement position from the high-electric power DUV laser the two at the wavelength of FHG with the 1-μm laser and at 193 nm. The the latest advancement of your sound-point out/fiber laser, plus the nonlinear optical crystals, prompts not merely the standard electrical power and also the beam high quality (coherence) with the DUV lasers to an unprecedented degree.
The standard power with the NIR laser nonetheless has the opportunity being enhanced to tens of watts like 70 W [26] If your double-pass configuration might be utilized for your Yb:YAG SCF amplifier phase. Therefore, Should the conversion efficiency of 31% from NIR to DUV may be even now preserved at this greater power problem, the common output electric power of your DUV laser at 258 nm could be greater than twenty W, which might certainly be a extraordinary electric power degree with the DUV laser and produce the unanticipated DUV laser machining success. What's more, for top-ability DUV laser, the UV damage in the nonlinear crystal, including the windows for CLBO crystal and also the mirrors, is another critical parameter for lasting and secure Procedure.
Conversely, the beam top quality of the higher electric power DUV laser would turn out to be worse due to additional severe thermal and nonlinear results. As a result, the frequency conversion procedures ought to be very carefully meant to mitigate the aforementioned results. Consequently, a high-electrical power DUV laser for the FHG of one μm with a good beam top quality may very well be attained and may be effective for acquiring the shorter wavelength DUV lasers for example 193 nm by SFG.
As a result of thermal lens result inside the sound-state lasers, if the heating administration is insufficient, It's not easy to get the stable-condition laser having a substantial electricity in addition to a substantial beam good quality concurrently. Just lately, with the event of The skinny disk laser and solitary-crystal fiber (SCF) laser, a substantial-power laser at the elemental wavelength (one μm) were recognized with a good beam good quality Despite a TEM00 manner beam [four,24], which might be excellent candidates for the elemental of the DUV laser generation. One more candidate for the fundamental is the significant-electrical power fiber laser which may very well be realized by coherent beam blend with M2 worth below 1.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics in the Nd:YAG fundamental check here laser wavelength. To be able to enhance the hurt threshold, lower CLBO surface area roughness, by ultra-precision machining, is required. Since the CLBO crystal has easy hydroscopic reaction and micro scratches in machining, ultra-exact machining with the CLBO crystal is a complicated technical dilemma.
Tunable ultraviolet laser resource dependant on good-point out dye laser technology and CsLiB6O10 harmonic generation
Its UV absorption edge reaches a hundred and eighty nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as substantial as that of KDP. CLBO crystals is often grown from your stoichiometric soften with reduce viscosity.
