The obtain bandwidth e.g. of Yb:KGW and Yb:KYW may be very large in contrast with that of Yb:YAG. This permits for large wavelength tunability and for Considerably shorter pulse durations from method-locked lasers. Values very well down below 100 fs have been achieved with passive method locking.
This can be a preview of membership material, log in by means of an establishment to examine obtain. Entry this article
Femtosecond laser dependant on Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, making sure productive Vitality conversion and large general performance in laser methods.
By substituting yttrium with ytterbium inside the crystal lattice of Yb:KYW because of the very similar sizes of those chemical elements around one hundred% of Yb-doping might be realized. This distinctive attribute permits ytterbium to take the area of yttrium with just about no disruption to the crystal’s lattice.
Right after air drying and subsequent cleaning with a cotton fabric soaked in alcohol, the film surface area confirmed no signs of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and they are used read more as lasing elements to create ultrashort (~ one hundred-two hundred fs) superior electric power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser techniques.
5 mm other than the middle with the beam caustic. So that you can Verify the manner matching simulation, we performed the experiment with Ng-Reduce crystal oscillator, which was made Beforehand As well as in a similar condition with simulation [11]. As revealed in Determine 3(b) with purple dots and line, the CW output electric power is highly depending on the posture of laser crystal as well as the experimental outcome coincides perfectly with simulation result. As a Be aware, multimode Procedure transpired in experiment if the size in the pump beam is bigger than TEM00 cavity mode and it triggers better CW output energy from the displacement region down below three.five mm.
For tungstates, the ytterbium doping focus can be very higher without having considerable quenching as the changed ions have an exceptionally comparable ion radius, as well as inter-ion length is pretty substantial.
Substantial-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
