All-strong-point out ultraviolet lasers are actually widely Employed in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of tiny volume, very long everyday living, significant performance, superior beam excellent, extensive tuning and narrow spectral line, etc. Using large energy around-infrared coherent light supply as the fundamental frequency supply depending on nonlinear tuning technological innovation, producing ultraviolet coherent radiation by multistage frequency conversion is thought to be an important strategy to produce the ultraviolet coherent light-weight source.
Compared to BBO it characteristics larger sized spectral and temperature acceptance, improved angle tolerance, in addition to a smaller sized wander-off angle. from 3289 $ shipping
In accordance with the proof-of-theory experiment, the conversion effectiveness of 23% implied the opportunity of reaching substantial-power at the second Stokes wavelength in the Raman laser. When 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 in excess of ten W. The design from the Raman laser cavity must be optimized so as to stay away from the injury from the M1 and diamond area.
The typical energy of the NIR laser even now has the potential to generally be improved to tens of watts like 70 W [26] if the double-go configuration could possibly be used to the Yb:YAG SCF amplifier phase. That's why, When the conversion efficiency of 31% from NIR to DUV can be even now maintained at this increased power issue, the standard output electrical power with the DUV laser at 258 nm could be a lot more than twenty W, which would be described as a extraordinary energy degree to the DUV laser and cause the unanticipated DUV laser machining success. Moreover, for top-power DUV laser, the UV harm from the nonlinear crystal, such as the windows for CLBO crystal along with the mirrors, is an additional crucial parameter for long lasting and stable Procedure.

LBO is also an outstanding nonlinear crystal which is often placed on the SHG from your NIR to your green. The DUV laser is often understood by two levels of SFG within the LBO crystals due to the fact there isn't any stage-matching angle for LBO to convert the inexperienced laser at 515 nm or 532 nm into the DUV directly by SHG [sixteen]. A short while ago, the NSBBF crystal has also revealed its potential to acquire a superior conversion performance from 532 nm to 266 nm. The stroll-off angle and deff on the NSBBF are Virtually much like Individuals of CLBO [17].

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the best non-linear crystal which generates ultraviolet harmonics with the Nd:YAG essential laser wavelength. In order to enhance the damage threshold, low CLBO area roughness, by extremely-precision machining, is necessary. Since the CLBO crystal has effortless hydroscopic reaction and micro scratches in machining, extremely-exact machining in the CLBO crystal is actually a tough technological dilemma.
Tunable ultraviolet laser resource determined by stable-point out dye laser technological know-how and CsLiB6O10 harmonic technology
Its UV absorption edge reaches a hundred and eighty nm. The productive nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as large as that of KDP. CLBO crystals is usually developed from your stoichiometric soften with decreased viscosity.
