The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is very huge in contrast with that of Yb:YAG. This permits for large wavelength tunability and for Substantially shorter pulse durations from mode-locked lasers. Values effectively underneath a hundred fs are actually achieved with passive mode locking.
Along with its use like a Raman crystal, KGW is also Employed in other optical purposes, for instance in laser methods and as a scintillator in healthcare imaging.
-switched manner. The bandwidth inside the orthogonal orientation was Evidently Substantially broader. The calculated Fourier transform limited pulse period was as shorter as sub-one hundred sixty fs. Underneath the configuration where The 2 crystals were being put in the exact same orientation, Using the seed input, the amplified pulse bandwidth was only 3 nm with a hundred and eighty μJ Electrical power when it broke the dichroic mirrors.
Amplified pulses by having an Electricity previously mentioned 2.five mJ may be expected by applying a better pump energy to the regenerative amplifier and rendering it function at the saturation stage. The laser fluence of ~one J/cm2 on the dichroic mirrors is believed being below the injury threshold of substantial-high quality dielectric-coated mirrors.

The black line denotes the configuration With all the crystals positioned in a similar orientation, while the crimson line is underneath the configuration of crystals placed in orthogonal orientation.
Though BGO and LT manufactured the narrowest SC spectra (slightly less than 1.5 optical octaves), they may be seen as quite desirable nonlinear elements for broadband SC era with pumping at more time laser wavelengths. Owing to its big nonlinearity, BGO exhibited the lowest SC era threshold (seventy eight nJ) Amongst the click here investigated resources, which is 25 % lower than in KGW and will be regarded as exceptional nonlinear content for incredibly small-threshold SC technology. The noticed secure and durable harm-cost-free overall performance of BGO and GGG at two hundred kHz pulse repetition price indicates that these nonlinear materials have a possible for SC technology at even larger, MHz, repetition rates. Additionally, these products offer SC radiation with an outstanding list of parameters which are important for apps in higher velocity spectroscopy and imaging that make use of bulk-created SC, see e.g.seventeen,eighteen,19,20.
