The comparison with Eyeglasses is suitable For the reason that significant attain bandwidth lets e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We current a twin-crystal Yb:KGW laserthat iscapable to function like a Q-switched oscillator with output electricity nearly 24 W and pulse duration of twenty ns,or to be a regenerative amplifier with output power as much as 21 W and pulse duration below two hundred fs immediately after compression of chirped pulses. Both equally lasers have great beam excellent with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, guaranteeing economical energy conversion and higher functionality in laser programs.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW mainly because of the comparable sizes of these chemical features around one hundred% of Yb-doping can be accomplished. This exclusive characteristic permits ytterbium to go ahead and take position of yttrium with virtually no disruption towards the crystal’s lattice.
The monoclinic crystal structures results in a natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization reduction.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and therefore are made use of as lasing elements to crank out ultrashort (~ one hundred-200 fs) high energy pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser methods.
Tungstates have a tendency to get higher Raman coefficients (�?Raman scattering). Consequently, they're able to crank out considerable Raman get at reasonable optical intensities. It can be done to utilize the laser crystal itself as a Raman converter.
For tungstates, the ytterbium doping focus can be quite substantial with no substantial quenching as the replaced ions have an exceedingly comparable ion radius, along with the inter-ion length is fairly significant.
Large-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
