5 Essential Elements For CLBO Crystal

All-stable-state ultraviolet lasers are actually commonly used in the fields of mechanical flaw detection, lithography, micromachining and drugs for the benefits of small quantity, lengthy daily life, superior efficiency, good beam high-quality, wide tuning and slender spectral line, and so forth. Employing substantial energy in close proximity to-infrared coherent gentle supply as the elemental frequency resource based upon nonlinear tuning technological know-how, generating ultraviolet coherent radiation by multistage frequency conversion is viewed as a crucial technique to create the ultraviolet coherent mild source.

In accordance with the proof-of-basic principle experiment, the conversion performance of 23% implied the potential for achieving higher-electricity at the next Stokes wavelength of your Raman laser. If your pump laser of 1078 nm can be received at the normal energy of 50 W, the output ability of its 2nd Stokes wavelength at 1512 nm might be in excess of ten W. The design in the Raman laser cavity should be optimized to be able to stay away from the hurt of your M1 and diamond area.

The important thing dilemma of ultraviolet coherent mild source predominantly focuses on the event of nonlinear optical frequency conversion crystal in ultraviolet band. The nonlinear optical crystal is one of the conditions for frequency transformation, so The expansion, dimensions, hurt resistance, conversion effectiveness and allowable parameter choice of nonlinear optical crystal are required A growing number of.

LBO is usually a wonderful nonlinear crystal which is usually placed on the SHG from your NIR for the green. The DUV laser is frequently recognized by two levels of SFG from the LBO crystals considering the fact that there's no period-matching angle for LBO to convert the eco-friendly laser at 515 nm or 532 nm to the DUV directly by SHG [16]. Lately, the NSBBF crystal has also demonstrated its probable to acquire a substantial conversion performance from 532 nm to 266 nm. The walk-off angle and deff in the NSBBF are almost similar to All those of CLBO [17].

On one other aspect, the ability scaling with the NIR laser is yet another factor to improve the normal electric power of the 193-nm DUV laser. Because of the insufficient the higher-power amplification Alternative with the NIR laser (by way of example at 1553 nm), nonlinear frequency processes such as optical parameter oscillation (OPO) can be applied to build a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength as well as obtaining relative larger ability [21]. Not long ago, a diamond Raman laser showed its capability in acquiring a large power plus a large conversion performance on the 1st Stokes in the one-μm laser [22,23], which suggests the chance to generally be applied while in the 193-nm DUV laser era on account of its superior Raman gain and large frequency shift.

The beam profile revealed in Figure 7b demonstrated a very good beam top quality as on the list of merits of Raman laser, which might be helpful to make a 193-nm DUV laser with a top quality beam.

The development from the 193-nm laser was check here shown by phases of SFG. So that you can scale the DUV laser power effectively, a brand new thought of your 193-nm DUV laser technology is offered based on the diamond Raman laser.
