On this paper, The brand new lapping slurry and polishing slurry are introduced. As well as deliquescence degree of CLBO is fallen to least expensive. A fresh Doing the job technologies can be adopted. Immediately after tough sprucing, the concentration of extremely-precision sprucing slurry is increased appropriately. So does the ultra-precision polishing speed, along with the wiping pace is quicker compared to deliquescence speed. The CLBO crystal surface area roughness can realize 1nm and maintain the surface quality perfectly. Entry by way of your institution

As an example, The present concave OC could be replaced by a plane mirror which could mitigate the ability density within the area of M1 as well as diamond. Additionally, making use of high problems threshold coatings for M1 and diamond would also improve the output ability with no damages. Then, the NIR laser within the 2nd Stokes wavelength could possibly be superior enough, along with its great beam high-quality, to make the ultimate DUV laser at 193 nm using a high regular power.

Because of the thermal lens influence while in the sound-point out lasers, If your heating management is inadequate, It's not necessarily effortless to obtain the reliable-state laser that has a large ability along with a significant beam top quality concurrently. A short while ago, with the development of The skinny disk laser and one-crystal fiber (SCF) laser, a substantial-energy laser at the basic wavelength (one μm) had been realized with a fantastic beam high quality Despite having a TEM00 method beam [four,24], which would be great candidates for the elemental of the DUV laser technology. A further candidate for the elemental is definitely the high-energy fiber laser which might be achieved by coherent beam mixture with M2 benefit less than one.
On one other side, the facility scaling of the NIR laser is another element to boost the typical electrical power in the 193-nm DUV laser. As a result of lack of the high-ability amplification Alternative with the NIR laser (such as at 1553 nm), nonlinear frequency procedures for instance optical parameter oscillation (OPO) could possibly be placed on create a wavelength converter by shifting the wavelength from 1 μm to the specified wavelength in addition to acquiring relative bigger electrical more info power [21]. A short while ago, a diamond Raman laser showed its potential in acquiring a significant electrical power plus a significant conversion performance on the 1st Stokes of your one-μm laser [22,23], which implies the possibility for being utilized from the 193-nm DUV laser technology because of its higher Raman obtain and enormous frequency shift.

Cesium Lithium Borate (CsLiB6O10 or CLBO) is the simplest non-linear crystal which generates ultraviolet harmonics on the Nd:YAG fundamental laser wavelength. To be able to enhance the damage threshold, small CLBO surface area roughness, by ultra-precision machining, is necessary. Since the CLBO crystal has effortless hydroscopic reaction and micro scratches in machining, ultra-specific machining on the CLBO crystal can be a hard complex difficulty.
Tunable ultraviolet laser supply based upon stable-point out dye laser technology and CsLiB6O10 harmonic technology
Its UV absorption edge reaches one hundred eighty nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as significant as that of KDP. CLBO crystals could be grown within the stoichiometric melt with reduce viscosity.
