The 2-Minute Rule for CLBO Crystal

In this particular paper, The brand new lapping slurry and sharpening slurry are released. And also the deliquescence degree of CLBO is fallen to least expensive. A brand new Doing work technology is likewise adopted. Following rough polishing, the concentration of extremely-precision polishing slurry is greater thoroughly. So does the extremely-precision polishing speed, plus the wiping velocity is quicker when compared to the deliquescence pace. The CLBO crystal floor roughness can achieve 1nm and keep the area good quality perfectly. Obtain as a result of your institution

Compared to BBO it capabilities bigger spectral and temperature acceptance, greater angle tolerance, in addition to a lesser wander-off angle. from 3289 $ supply

According to the proof-of-theory experiment, the conversion effectiveness of 23% implied the potential of obtaining significant-power at the second Stokes wavelength from the Raman laser. In the event the pump laser of 1078 nm may be acquired at the typical energy of 50 W, the output electricity of its 2nd Stokes wavelength at 1512 nm may very well be much more than ten W. The look of your Raman laser cavity should be optimized in order to steer clear of the hurt on the M1 and diamond surface area.

The normal electrical power of the NIR laser however has the prospective to generally be improved to tens of watts such as 70 W [26] When the double-move configuration can be used with the Yb:YAG SCF amplifier phase. Therefore, Should the conversion efficiency of 31% from NIR to DUV can be nevertheless managed at this greater electric power problem, the typical output power of your DUV laser at 258 nm might be over 20 W, which might be a impressive ability degree for the DUV laser and bring about the unanticipated DUV laser machining benefits. Additionally, for prime-electricity DUV laser, the UV problems with the nonlinear crystal, including the windows for CLBO crystal and also the mirrors, is another important parameter for long term and steady Procedure.

Both equally the 1040 nm and 1078 nm laser come from just one twin-wavelength Yb-doped fiber laser. Every single laser is amplified by phases of fiber amplifier and Yb-doped supplies amplifier, respectively.

On another facet, the facility scaling on the NIR laser is another component to raise the typical ability with the 193-nm DUV laser. A result of the not enough the large-ability amplification Remedy of your NIR laser (for example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) can be placed on create a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength in addition to obtaining relative greater electrical power [21]. Just lately, a diamond Raman laser confirmed its potential in obtaining a substantial energy along with a high conversion performance on the 1st Stokes in the 1-μm laser [22,23], which means the chance to get used during the 193-nm DUV laser technology on account of its substantial Raman obtain and enormous frequency change.

The beam profile revealed in Figure 7b demonstrated an excellent beam good quality as on the list of deserves of Raman laser, which might be useful to crank out a 193-nm DUV laser with a high quality beam.

The development in the 193-nm laser was shown by levels of SFG. To be able to scale the DUV laser electricity correctly, a brand read more new principle with the 193-nm DUV laser technology is introduced based on the diamond Raman laser.
