The 2-Minute Rule for CLBO Crystal
The 2-Minute Rule for CLBO Crystal
Blog Article
In this particular paper, The brand new lapping slurry and sprucing slurry are introduced. As well as the deliquescence diploma of CLBO is fallen to least expensive. A whole new Doing the job technology is additionally adopted. Immediately after tough sprucing, the focus of extremely-precision sharpening slurry is increased effectively. So does the ultra-precision polishing velocity, as well as wiping velocity is quicker in comparison to the deliquescence pace. The CLBO crystal surface area roughness can attain 1nm and preserve the surface high quality perfectly. Obtain by your institution
In comparison to BBO it options much larger spectral and temperature acceptance, better angle tolerance, plus a scaled-down wander-off angle. from 3289 $ supply

The average power of your NIR laser however has the likely for being enhanced to tens of watts for example 70 W [26] if the double-move configuration may be utilized for that Yb:YAG SCF amplifier stage. For this reason, In the event the conversion performance of 31% from NIR to DUV could possibly be continue to taken care of at this better power problem, the standard output electrical power with the DUV laser at 258 nm might be a lot more than twenty W, which might certainly be a outstanding electricity stage for that DUV laser and cause the unanticipated DUV laser machining success. Moreover, for high-energy DUV laser, the UV harm from the nonlinear crystal, including the Home windows for CLBO crystal as well as mirrors, is yet another significant parameter for lasting and steady operation.

Both of those the 1040 nm and 1078 nm laser originate from 1 dual-wavelength Yb-doped fiber laser. Every laser is amplified by phases of fiber amplifier and Yb-doped supplies amplifier, respectively.

During the scientific and industrial purposes, the beam high-quality of your DUV laser is usually a very important parameter. Significantly, the beam excellent on the DUV laser drastically has an effect on the laser machining outcomes. The beam quality of your DUV laser is set by that of the elemental laser along with the crystal for the frequency conversion. A short while ago, a large-power DUV laser (>10 W) at 258 nm was claimed using a beam high-quality of M2 < 1.5, which was produced by FHG of the Yb:YAG laser at 1030 nm using the CLBO crystal [13]. This laser would produce an improved laser machining final result in comparison with the past DUV lasers with larger M2.

The beam profile proven in Figure 7b demonstrated a good beam good quality as one of many deserves of Raman laser, which might be advantageous to make a 193-nm DUV laser with a high quality beam.
Its UV absorption edge reaches one hundred eighty nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as significant as that of KDP. CLBO crystals may be developed within the stoichiometric melt with lessen viscosity.
