The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly huge compared with that of Yb:YAG. This allows for broad wavelength tunability and for Significantly shorter pulse durations from mode-locked lasers. Values nicely beneath a hundred fs have been obtained with passive mode locking.
As well as its use to be a Raman crystal, KGW can also be Utilized in other optical applications, which include in laser programs and as a scintillator in clinical imaging.

In its elemental form, gadolinium has a silvery-white appearance. Gadolinium can be a unusual earth or lanthanide component that possesses exceptional Houses beneficial to specialised applications like semiconductor fabrication and nuclear reactor shielding. It's utilized for the two its higher magnetic instant (7.ninety fourμ B) As well as in phosphors and scintillator crystals. When complexed with EDTA ligands, it is utilised as an injectable contrast agent for MRIs. The ingredient is named after the Finnish chemist and geologist Johan Gadolin.
Though BGO and LT generated the narrowest SC spectra (a little fewer than one.5 optical octaves), they might be seen as quite interesting nonlinear elements for broadband SC technology with pumping at for a longer time laser wavelengths. Owing to its massive nonlinearity, BGO exhibited the lowest SC technology threshold (78 nJ) among the investigated resources, that's 25 % reduce than in KGW and will be considered as great nonlinear content for really small-threshold SC era. The noticed stable and durable damage-cost-free overall performance of BGO and GGG at two hundred kHz pulse repetition price indicates that these nonlinear resources have a potential for SC era at even higher, MHz, repetition rates. Also, these components provide SC radiation with an outstanding list of parameters that are essential for programs in high velocity spectroscopy and imaging that make use of bulk-created SC, see e.g.seventeen,eighteen,19,twenty.
The two-pump laser could give as many as one hundred twenty W ability. Around sixty% of the maximum pump electricity was applied within our experiment thinking about the lower general performance from the dichroic mirrors. Beneath this twin-crystal configuration, our cavity supports a a hundred W pump power input, as mentioned in Area 2.2. Significant-quality dichroic mirrors is going to be applied Sooner or later, and laser pulses are going to be stretched to an extended pulse length.
Despite the fact that BGO, GGG, YSO, LSO and LYSO often serve as laser hosts37, They are really primarily identified as productive scintillators, whose scintillation Homes are researched fairly well38. Nevertheless, the nonlinear optical properties of such crystals and so their opportunity to serve as nonlinear materials for SC technology specifically, and every other experiments regarding nonlinear check here propagation of intense femtosecond laser pulses, keep on being really poorly analyzed. Thus far, GGG, LT23,25 and YSO24 were being only sketchily tested for SC technology with Ti:sapphire laser pumping, on the other hand, to the top of our expertise, none of the investigated resources were examined with Yb-laser pumping, especially for what problems their efficiency at incredibly high (tens to a huge selection of kHz) pulse repetition premiums.
-switched laser output beneath the two crystal placement configurations. The black line denotes the configuration Using the crystals put in the identical orientation, even though the purple line is beneath the configuration of crystals put in orthogonal orientation.
The scattered photons have a different wavelength and Vitality than the incident photons, which produces a Raman spectrum.
KGW crystals are applied as Raman scattering resources given that they have powerful Raman scattering in a variety of various wavelengths. Whenever a laser beam is directed on to the crystal, the photons from the laser beam communicate with the crystal lattice, leading to a few of the photons to scatter in a unique route.
