Besides its use as being a Raman crystal, KGW can be used in other optical apps, for instance in laser techniques and for a scintillator in health-related imaging.
In contrast, the seed laser might be amplified to about 1 mJ beneath the orthogonal orientation configuration.

Circumstance Experiments of selected essential systems invented or co-invented by American Features in only the 1st 20 years of the century
Whilst BGO and LT produced the narrowest SC spectra (marginally less than 1.five optical octaves), they may be considered as quite appealing nonlinear components for broadband SC generation with pumping at longer laser wavelengths. Owing to its substantial nonlinearity, BGO exhibited the lowest SC era threshold (78 nJ) among the investigated supplies, that's twenty five % reduced than in KGW and will be considered as outstanding nonlinear substance for pretty lower-threshold SC generation. The noticed stable and durable problems-absolutely free effectiveness of BGO and GGG at 200 kHz pulse repetition level implies that these nonlinear resources have a potential for SC generation at even bigger, MHz, repetition premiums. What's more, these materials provide SC radiation with a great list of parameters which are important for apps in high velocity spectroscopy and imaging that employ bulk-produced SC, see e.g.17,eighteen,19,twenty.

Since its discovery in 19701,2, the point out on the art of supercontinuum (SC) era in bulk solid-condition supplies has achieved a high degree of maturity thanks to incredible development of ultrafast laser sources and elementary knowledge of the underlying Actual physical processes3,4. The complexity of Bodily effects fundamental SC generation is unveiled within the framework of femtosecond filamentation, which happens to be a universal phenomenon arising from nonlinear propagation of femtosecond laser pulses in transparent materials5. In more realistic terms, the attainable spectral extent of SC radiation is determined by the material Houses, such as linear and nonlinear indexes of refraction and Electricity bandgap, which along with the laser wavelength define the significant ability for self-focusing (which has to get exceeded for a light-weight filament to form) and clamping depth of a light-weight filament (which is proportional on the buy of multiphoton absorption), respectively.
