During this paper, the new lapping slurry and sprucing slurry are introduced. Along with the deliquescence diploma of CLBO is fallen to most affordable. A new Doing work know-how can also be adopted. Soon after rough sharpening, the concentration of ultra-precision polishing slurry is improved appropriately. So does the extremely-precision polishing pace, plus the wiping velocity is quicker than the deliquescence speed. The CLBO crystal surface roughness can attain 1nm and preserve the floor excellent perfectly. Entry by means of your institution

In accordance with the evidence-of-theory experiment, the conversion efficiency of 23% implied the potential of attaining substantial-electricity at the 2nd Stokes wavelength from the Raman laser. If your pump laser of 1078 nm could possibly be acquired at the common electric power of fifty W, the output energy of its 2nd Stokes wavelength at 1512 nm might be over ten W. The look on the Raman laser cavity ought to be optimized as a way to stay away from the hurt on the M1 and diamond surface area.

The standard power of your NIR laser still has the probable being improved to tens of watts including 70 W [26] When the double-pass configuration could possibly be utilized to the Yb:YAG SCF amplifier stage. Hence, In case the conversion efficiency of 31% from NIR to DUV may very well be nevertheless managed at this larger ability problem, the standard output energy in the DUV laser at 258 nm could be a lot more than twenty W, which might be a amazing power degree for that DUV laser and lead to the unanticipated DUV laser machining benefits. In addition, for high-electric power DUV laser, the UV damage of your nonlinear crystal, such as the Home windows for CLBO crystal and the mirrors, is another important parameter for long term and secure operation.

LBO is also an outstanding nonlinear crystal which is often placed on the SHG through the NIR into the green. The DUV laser is normally recognized by two stages of SFG inside the LBO crystals considering that there is not any period-matching angle for LBO to transform the green laser at 515 nm or 532 nm into the DUV specifically by SHG [16]. Lately, the NSBBF crystal has also demonstrated its prospective to acquire a superior conversion performance from 532 nm to 266 nm. The stroll-off angle and deff in the NSBBF are Virtually similar to those of CLBO [seventeen].

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the simplest non-linear crystal which generates ultraviolet harmonics with the Nd:YAG basic laser wavelength. To be more info able to enhance the problems threshold, lower CLBO floor roughness, by ultra-precision machining, is required. Since the CLBO crystal has effortless hydroscopic response and micro scratches in machining, ultra-specific machining on the CLBO crystal is actually a difficult complex dilemma.

Tunable ultraviolet laser source according to strong-state dye laser technological innovation and CsLiB6O10 harmonic era
