All-solid-state ultraviolet lasers have already been extensively used in the fields of mechanical flaw detection, lithography, micromachining and medication for some great benefits of compact volume, lengthy daily life, significant effectiveness, great beam quality, huge tuning and narrow spectral line, etc. Making use of high electricity close to-infrared coherent light-weight source as the basic frequency resource depending on nonlinear tuning technology, generating ultraviolet coherent radiation by multistage frequency conversion is considered to be an essential way to establish the ultraviolet coherent mild resource.

Both of those the 1040 nm and 1078 nm laser come from one particular dual-wavelength Yb-doped fiber laser. Every laser is amplified by levels of fiber amplifier and Yb-doped supplies amplifier, respectively.
On another facet, the facility scaling from the NIR laser is yet another component to improve the typical ability on the 193-nm DUV laser. Mainly because of the lack of the check here higher-electricity amplification solution of your NIR laser (by way of example at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) may be applied to develop a wavelength converter by shifting the wavelength from one μm to the specified wavelength and obtaining relative higher power [21]. Just lately, a diamond Raman laser confirmed its capacity in acquiring a high energy plus a large conversion performance on the 1st Stokes with the 1-μm laser [22,23], which implies the likelihood to become used during the 193-nm DUV laser technology thanks to its higher Raman obtain and enormous frequency shift.

The heartbeat period of the next Stokes mild was shortened to five ns as shown in Figure 7a, one-shot image from your oscilloscope, that is a standard phenomenon in Raman laser [44] when the pulse period on the pump laser was ten ns.
Also, combining the reliable-condition laser with other nonlinear process for instance stimulated Raman scattering, NIR lasers might be reached at new wavelengths with significant energy and substantial beam high quality, which was analyzed via the evidence-of-theory experiment. This Raman laser plan provides a completely new path to the large-power DUV laser, Specifically within the wavelength of 193 nm.
Tunable ultraviolet laser supply dependant on sound-condition dye laser technological know-how and CsLiB6O10 harmonic generation
Its UV absorption edge reaches a hundred and eighty nm. The effective nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about twice as substantial as that of KDP. CLBO crystals could be grown with the stoichiometric melt with lessen viscosity.
