We summarized The existing growth status on the higher-ability DUV laser the two at the wavelength of FHG on the one-μm laser and at 193 nm. The modern development on the solid-condition/fiber laser, together with the nonlinear optical crystals, prompts not simply the average energy and also the beam quality (coherence) in the DUV lasers to an unparalleled stage.
The real key problem of ultraviolet coherent light resource primarily focuses on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is without doubt one of the conditions for frequency transformation, so The expansion, sizing, destruction resistance, conversion performance and allowable parameter choice of nonlinear optical crystal are expected more and more.
Then again, the beam high-quality of the higher energy DUV laser would grow to be worse as a result of far more serious thermal and nonlinear effects. Hence, the frequency conversion procedures really should be diligently meant to mitigate the aforementioned outcomes. As a result, a large-energy DUV laser in the FHG of one μm with a superb beam top quality may be obtained and may be advantageous for obtaining the shorter wavelength DUV lasers such as 193 nm by SFG.
As a result of thermal lens impact inside the sound-state lasers, Should the heating management is inadequate, It's not easy to get the solid-condition laser which has a large power plus a high beam high quality at the same time. Just lately, with the event of The skinny disk laser and one-crystal fiber (SCF) laser, a significant-power laser at the fundamental wavelength (1 μm) had been recognized with a fantastic beam high-quality even with a TEM00 mode beam [four,24], which might be superior candidates for the elemental of your DUV laser technology. A further prospect for the elemental is definitely the superior-power fiber laser which could be achieved by coherent beam mix with M2 price fewer than one.
On the opposite side, the facility scaling with the NIR laser is an additional aspect to enhance the normal electrical power of your 193-nm DUV laser. Due to insufficient the superior-electricity amplification Alternative on the NIR laser (for instance at 1553 nm), nonlinear frequency procedures such as optical parameter oscillation (OPO) may check here very well be placed on create a wavelength converter by shifting the wavelength from one μm to the specified wavelength as well as obtaining relative greater electric power [21]. Recently, a diamond Raman laser showed its potential in attaining a significant ability along with a large conversion efficiency on the 1st Stokes on the 1-μm laser [22,23], which implies the possibility to become used during the 193-nm DUV laser technology as a consequence of its superior Raman obtain and large frequency change.

You might also Check out the attainable accessibility through particular account by logging in or/and Test entry by means of your institution.
Furthermore, combining the good-state laser with other nonlinear approach including stimulated Raman scattering, NIR lasers can be accomplished at new wavelengths with large electric power and high beam high quality, which was examined because of the evidence-of-theory experiment. This Raman laser plan delivers a completely new path to the significant-ability DUV laser, Primarily for the wavelength of 193 nm.
