In this particular paper, The brand new lapping slurry and polishing slurry are launched. Plus the deliquescence diploma of CLBO is fallen to lowest. A fresh Performing engineering is additionally adopted. Following tough sprucing, the focus of ultra-precision sprucing slurry is greater appropriately. So does the extremely-precision sprucing velocity, and also the wiping pace is faster as opposed to deliquescence velocity. The CLBO crystal surface roughness can attain 1nm and maintain the area high-quality very well. Entry as a result of your establishment

According to the proof-of-theory experiment, the conversion performance of 23% implied the potential for reaching higher-electricity at the next Stokes wavelength with the Raman laser. If the pump laser of 1078 nm might be acquired at the standard energy of 50 W, the output power of its 2nd Stokes wavelength at 1512 nm could be more than 10 W. The design of the Raman laser cavity really should be optimized so that you can steer clear of the destruction of the M1 and diamond surface area.
The important thing issue of ultraviolet coherent gentle resource mainly focuses on the development of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal has become the conditions for frequency transformation, so the growth, measurement, injury resistance, conversion effectiveness and allowable parameter array of nonlinear optical crystal are demanded An increasing number of.

Both the 1040 nm and 1078 nm laser originate from one twin-wavelength Yb-doped fiber laser. Each individual laser is amplified by levels of fiber amplifier and Yb-doped products amplifier, respectively.
On the opposite aspect, the ability scaling in the NIR laser is another aspect to increase the ordinary energy of your 193-nm DUV laser. Mainly because of the deficiency of the higher-ability amplification Remedy from the NIR laser (for example at 1553 nm), nonlinear frequency processes which include optical parameter oscillation (OPO) may be placed on develop a here wavelength converter by shifting the wavelength from one μm to the specified wavelength along with obtaining relative bigger electrical power [21]. Not long ago, a diamond Raman laser confirmed its ability in attaining a superior electrical power in addition to a high conversion effectiveness with the 1st Stokes of your one-μm laser [22,23], which means the possibility to become applied while in the 193-nm DUV laser generation as a result of its large Raman obtain and large frequency change.

The heartbeat length of the next Stokes light-weight was shortened to five ns as demonstrated in Figure 7a, just one-shot photograph from your oscilloscope, which is a typical phenomenon in Raman laser [forty four] even though the heartbeat period of your pump laser was 10 ns.

The beam profile shown in Determine 7b demonstrated a fantastic beam quality as on the list of deserves of Raman laser, which might be beneficial to produce a 193-nm DUV laser with a high quality beam.
