All-strong-condition ultraviolet lasers are widely used in the fields of mechanical flaw detection, lithography, micromachining and medicine for the advantages of modest volume, prolonged daily life, substantial efficiency, good beam quality, vast tuning and narrow spectral line, etcetera. Using higher electric power around-infrared coherent mild resource as the basic frequency source determined by nonlinear tuning technological know-how, producing ultraviolet coherent radiation by multistage frequency conversion is regarded as a significant method to acquire the ultraviolet coherent light supply.

Both of those the 1040 nm and 1078 nm laser originate from one particular dual-wavelength Yb-doped fiber laser. Every laser is amplified by phases of fiber amplifier and Yb-doped supplies amplifier, respectively.
On the other aspect, the ability scaling on the NIR laser is another aspect to enhance the normal ability with the 193-nm DUV laser. Due to insufficient the superior-electricity amplification Alternative on the NIR laser (for instance at 1553 nm), nonlinear frequency procedures including optical parameter oscillation (OPO) can be applied to produce a wavelength converter by shifting the wavelength from one μm to the desired wavelength along with getting relative greater electricity [21]. Recently, a diamond Raman laser showed its potential in acquiring a significant power as well as a significant conversion performance within the 1st Stokes of the one-μm laser [22,23], which means the likelihood being used from the 193-nm DUV laser technology as a consequence of its significant Raman get and large frequency shift.
Crylink is an open up System, just as our mission is to attach price, Crylink believes that every person and each corporation has exclusive worth, and we hope to connect with important you to deliver value and replicate worth check here alongside one another.

The heart beat length of the second Stokes gentle was shortened to 5 ns as demonstrated in Figure 7a, one-shot image from the oscilloscope, that is a standard phenomenon in Raman laser [44] when the heartbeat period from the pump laser was 10 ns.
Also, combining the reliable-point out laser with other nonlinear method for example stimulated Raman scattering, NIR lasers may very well be achieved at new wavelengths with high ability and higher beam high quality, which was examined by the evidence-of-principle experiment. This Raman laser scheme supplies a whole new path to the superior-energy DUV laser, Specially within the wavelength of 193 nm.
Tunable ultraviolet laser supply determined by stable-condition dye laser technological know-how and CsLiB6O10 harmonic technology
Its UV absorption edge reaches one hundred eighty nm. The helpful nonlinear optical coefficient of CLBO for frequency doubling at 1064nm is about 2 times as massive as that of KDP. CLBO crystals could be developed in the stoichiometric soften with reduced viscosity.
