However, so that you can course of action the crystal is quite Sophisticated manufacturing techniques are expected. Because the dawn of the crystal, working on this problem, we at the moment are the sole corporation on earth which might be processed On this crystal.

Based on the proof-of-theory experiment, the conversion performance of 23% implied the possibility of obtaining superior-power at the second Stokes wavelength in the Raman laser. In case the pump laser of 1078 nm may very well be received at the normal electric power of fifty W, the output electric power of its 2nd Stokes wavelength at 1512 nm could be more than ten W. The look with the Raman laser cavity should be optimized in order to steer clear of the hurt from the M1 and diamond area.
The normal ability from the NIR laser still has the opportunity to get improved to tens of watts which include 70 W [26] When the double-go configuration may be utilized for that Yb:YAG SCF amplifier stage. As a result, In case the conversion effectiveness of 31% from NIR to DUV could be however maintained at this increased ability condition, the typical output power on the DUV laser at 258 nm can be over twenty W, which might certainly be a outstanding electrical power stage for your DUV laser and cause the unanticipated DUV laser machining success. Moreover, for top-power DUV laser, the UV damage of your nonlinear crystal, including the windows for CLBO crystal along with the mirrors, is an additional crucial parameter for long-term and stable Procedure.

On one other facet, the ability scaling with the NIR laser is an additional element to boost the ordinary electricity from the 193-nm DUV laser. Mainly because of the insufficient the large-electricity amplification Resolution with the NIR laser (for instance at 1553 nm), nonlinear frequency processes for instance optical parameter oscillation (OPO) could be applied to develop a wavelength converter by shifting the wavelength from 1 μm to the desired wavelength together with getting relative bigger power [21]. Lately, a diamond Raman laser showed its potential in acquiring a superior ability and a high conversion performance for the 1st Stokes on the 1-μm laser [22,23], which implies the chance to get applied in the 193-nm DUV laser technology on account of its superior Raman attain and huge frequency change.

The heart beat period of the second Stokes light-weight was shortened to 5 ns as proven in Determine 7a, a single-shot image within the oscilloscope, which happens to be a common phenomenon in Raman laser [44] when the heart beat duration of the pump laser was ten ns.

The beam profile demonstrated in Figure 7b demonstrated a superb beam good quality as among the list of deserves of Raman laser, which would be advantageous to generate a 193-nm DUV laser with get more info a high quality beam.

The development with the 193-nm laser was demonstrated by phases of SFG. In an effort to scale the DUV laser power efficiently, a completely new notion with the 193-nm DUV laser technology is presented determined by the diamond Raman laser.
