Based on the proof-of-theory experiment, the conversion efficiency of 23% implied the potential of attaining higher-energy at the second Stokes wavelength of your Raman laser. Should the pump laser of 1078 nm may very well be received at the common energy of fifty W, the output electricity of its 2nd Stokes wavelength at 1512 nm may be a lot more than 10 W. The design from the Raman laser cavity must be optimized in an effort to stay away from the harm of the M1 and diamond area.
The crucial element issue of ultraviolet coherent gentle resource primarily focuses on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is amongst the ailments for frequency transformation, so the growth, dimensions, damage resistance, conversion effectiveness and allowable parameter array of nonlinear optical crystal are essential Increasingly more.
Alternatively, the beam excellent of the better energy DUV laser would become worse as a consequence of additional major thermal and nonlinear effects. Therefore, the frequency conversion procedures ought to be cautiously intended to mitigate the aforementioned effects. Consequently, a significant-energy DUV laser within the FHG of one μm with a good beam excellent may be acquired and can be advantageous for getting the shorter wavelength DUV lasers for instance 193 nm by SFG.
LBO is additionally an excellent nonlinear crystal which is usually placed on the SHG from your NIR to your green. The DUV laser is frequently realized by two phases of SFG from the LBO crystals given that there is not any phase-matching angle for LBO to transform the green laser at 515 nm or 532 nm on the DUV straight by SHG [sixteen]. Recently, the NSBBF crystal has also proven its probable to acquire a higher conversion effectiveness from 532 nm to 266 nm. The stroll-off angle and deff of your NSBBF are Nearly much like All those of CLBO [seventeen].
On the opposite side, the facility scaling in the NIR laser is another part to raise the typical ability on the 193-nm DUV laser. As a result of not enough the substantial-energy amplification Alternative in the NIR laser (for example at 1553 nm), nonlinear frequency procedures including optical parameter oscillation (OPO) could possibly be placed on create a wavelength converter by shifting the wavelength from one μm to the specified wavelength as well as acquiring relative bigger electrical power [21]. A short while ago, a diamond Raman laser showed its potential in acquiring a higher electric power and a large conversion performance within the 1st Stokes from the 1-μm laser [22,23], which means the chance to be applied while in the 193-nm DUV laser technology thanks to its high Raman gain and huge frequency shift.

The heartbeat duration of the 2nd Stokes light was shortened to five ns as demonstrated in Determine 7a, one-shot picture from the oscilloscope, and that is a common phenomenon in Raman laser [forty four] whilst the pulse duration from the pump laser was 10 ns.

Its UV absorption edge reaches 180 nm. The powerful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as large as that of KDP. CLBO crystals could be developed from the stoichiometric melt with lessen viscosity.
The development with the 193-nm laser was demonstrated by levels of SFG. As a way to scale the DUV laser ability properly, a new principle of the 193-nm DUV laser era is introduced depending on the diamond Raman laser.
