The get bandwidth e.g. of Yb:KGW and Yb:KYW may be very big in comparison with that of Yb:YAG. This permits for large wavelength tunability and for Significantly shorter pulse durations from manner-locked lasers. Values perfectly underneath one hundred fs are already attained with passive mode locking.
The comparison with glasses is appropriate For the reason that massive gain bandwidth allows e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
Femtosecond laser dependant on Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the heart beat

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW mainly because of the very similar measurements of these chemical features approximately 100% of Yb-doping could be realized. This exclusive characteristic permits ytterbium to go ahead and take location of yttrium with virtually no disruption on the crystal’s lattice.
Immediately after air drying and subsequent cleaning by using a cotton fabric soaked in Liquor, the movie surface showed no indications of peeling or scratches.

Higher-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
The thermal conductivity of popular double tungstates is on the order to three–4 W/(K m) �?which is not negative compared with other laser crystals (While quite a few instances below for YAG), and fairly massive in comparison Together with the thermal conductivity of standard glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, can be a exceptional material that performs an important function in laser technological know-how. Its Most important purpose is to make ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
