The gain bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly big in comparison with that of Yb:YAG. This permits for large wavelength tunability and for A lot shorter pulse durations from method-locked lasers. Values very well down below a hundred fs happen to be accomplished with passive mode locking.

The comparison with glasses is acceptable For the reason that large gain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to compete with glass lasers.

Femtosecond laser based on Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heartbeat

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by effective linear arrays of semiconductor injection lasers owning fiber output. To forestall spectral narrowing through amplification and the corresponding lengthening of your amplified pulse when it can be compressed, a combination of two Yb:KYW crystals were applied, Together with the spectral maxima on the amplification shifted relative to each other and with spectral profiling on the amplified radiation.

Following air drying and subsequent cleansing that has a cotton cloth soaked in Liquor, the movie surface showed no indications of peeling or scratches.

Tungstates are likely to have superior Raman coefficients (�?Raman scattering). here Hence, they could generate significant Raman achieve at reasonable optical intensities. It is possible to use the laser crystal alone being a Raman converter.

For tungstates, the ytterbium doping concentration can be quite large with out considerable quenching because the changed ions have an incredibly identical ion radius, as well as inter-ion distance is comparatively huge.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is usually a remarkable product that plays an essential job in laser technological know-how. Its Principal perform would be to deliver ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
