All-stable-point out ultraviolet lasers are actually greatly Employed in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of tiny volume, extended lifetime, superior performance, superior beam good quality, large tuning and slender spectral line, etcetera. Using high electrical power close to-infrared coherent light-weight supply as the elemental frequency supply based upon nonlinear tuning technological know-how, making ultraviolet coherent radiation by multistage frequency conversion is thought to be an important technique to build the ultraviolet coherent light-weight supply.
In comparison to BBO it options greater spectral and temperature acceptance, far better angle tolerance, along with a lesser stroll-off angle. from 3289 $ supply
Based on the evidence-of-theory experiment, the conversion efficiency of 23% implied the potential for reaching large-energy at the 2nd Stokes wavelength with the Raman laser. In case the pump laser of 1078 nm could possibly be obtained at the standard electrical power of fifty W, the output electricity of its 2nd Stokes wavelength at 1512 nm could be more than ten W. The design of your Raman laser cavity really should be optimized in an effort to avoid the destruction from the M1 and diamond floor.
The standard ability on the NIR laser still has the opportunity for being improved to tens of watts like 70 W [26] When the double-go configuration could be used for the Yb:YAG SCF amplifier phase. Therefore, Should the conversion effectiveness of 31% from NIR to DUV can be nevertheless managed at this larger ability problem, the normal output power of your DUV laser at 258 nm can be a lot more than twenty W, which would be described as a outstanding electric power amount for your DUV laser and cause the unanticipated DUV laser machining success. In addition, for prime-electricity DUV laser, the UV hurt with the nonlinear crystal, such as the windows for CLBO crystal as well as the mirrors, is another important parameter for long term and secure operation.

LBO can also be a fantastic nonlinear crystal which is often placed on the SHG from the NIR towards the environmentally friendly. The DUV laser is normally realized by two levels of SFG during the LBO crystals considering that there isn't a stage-matching angle for LBO to convert the green laser at 515 nm or 532 nm towards the DUV immediately by SHG [16]. Not too long ago, the NSBBF crystal has also proven its prospective to get a substantial conversion effectiveness from 532 nm to 266 nm. The stroll-off angle and deff with the NSBBF are Just about just like All those of CLBO [17].

The pulse period of the next Stokes mild was shortened to five ns as demonstrated in Figure 7a, a single-shot photograph through the oscilloscope, which can be a common phenomenon in Raman laser [44] whilst the heart beat duration on the pump laser was 10 ns.

Its UV absorption edge reaches 180 nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about two times as huge as that of KDP. CLBO crystals may be grown within the stoichiometric melt with decreased viscosity.
