Previous function showed that the dual-crystal configuration can be used to compensate to the thermal lensing impact[

As well as its use to be a Raman crystal, KGW is also used in other optical purposes, which include in laser programs and being a scintillator in health-related imaging.
], but it would increase a lot more cost to this element. The intra-cavity spectral gain curve may be modulated by inserting an etalon that cuts down the particular gain in the wavelength with the maximum acquire issue[
The calculated Slash-off wavelengths on the quick-wavelength side are in line with the final craze of blue-shifted spectral broadening on the bandgap of nonlinear product. The many nonlinear resources made affordable red-shifted spectral broadenings underneath circumstances of exceptional pump pulse energies, with the most important crimson-change exceeding 2000 nm measured in GGG crystal. Our final results discovered that GGG and BGO (which also experienced the lowest supercontinuum technology threshold) provide sturdy, optical destruction-absolutely free efficiency in a laser repetition charge of two hundred kHz, suggesting that these supplies are superior choices to YAG and KGW for low threshold, significant common ability supercontinuum era inside the near- and shorter-wave infrared spectral ranges. We also demonstrated that scintillating Houses of bulk materials can be easily analyzed from the filamentation routine, via multiphoton excitation utilizing around-infrared femtosecond laser pulses.

Comparison of spectral Electrical power densities of supercontinua generated during the problems of best pumping from the investigated supplies.

]. The twin-crystal configuration lowers the thermal load on Every single crystal whilst sustaining a superior get, and facilitates the compensation of every one’s website thermal lensing impact. Hence, the laser cavity can get the job done with a big steadiness selection more than the thermal lensing influence variation.
