The 2-Minute Rule for CLBO Crystal

The 2-Minute Rule for CLBO Crystal

Blog Article

All-strong-condition ultraviolet lasers are already commonly Utilized in the fields of mechanical flaw detection, lithography, micromachining and medication for the benefits of modest quantity, extensive everyday living, significant effectiveness, very good beam good quality, vast tuning and narrow spectral line, etcetera. Employing superior ability in close proximity to-infrared coherent light supply as the fundamental frequency supply determined by nonlinear tuning technological innovation, generating ultraviolet coherent radiation by multistage frequency conversion is viewed as a crucial way to produce the ultraviolet coherent light-weight resource.

We summarized The existing growth position in the higher-power DUV laser both of those with the wavelength of FHG from the one-μm laser and at 193 nm. The recent progress from the stable-state/fiber laser, as well as the nonlinear optical crystals, prompts not merely the standard power but in addition the beam high quality (coherence) on the DUV lasers to an unparalleled amount.

The typical power of your NIR laser however has the opportunity being improved to tens of watts like 70 W [26] if the double-move configuration might be used for your Yb:YAG SCF amplifier phase. Therefore, In the event the conversion performance of 31% from NIR to DUV could possibly be nevertheless maintained at this increased energy affliction, the average output electricity of your DUV laser at 258 nm might be a lot more than twenty W, which would certainly be a extraordinary electric power degree for your DUV laser and bring on the unanticipated DUV laser machining success. Moreover, for high-power DUV laser, the UV damage of the nonlinear crystal, such as the windows for CLBO crystal as well as the mirrors, is another essential parameter for long-term and secure operation.

The beam profile shown in Figure 7b demonstrated an excellent beam good quality as on the list of deserves of Raman laser, which might be beneficial to generate a 193-nm DUV laser with a check here high quality beam.
