The acquire bandwidth e.g. of Yb:KGW and Yb:KYW is rather large in comparison with that of Yb:YAG. This enables for large wavelength tunability and for A lot shorter pulse durations from mode-locked lasers. Values properly underneath a hundred fs have been accomplished with passive method locking.

We current a twin-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output electric power approximately 24 W and pulse size of 20 ns,or being a regenerative amplifier with output ability nearly 21 W and pulse period down below two hundred fs immediately after compression of chirped pulses. The two lasers have great beam excellent with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals display robust peaks at 980 nm and 1030 nm, respectively, guaranteeing economical energy conversion and high overall performance in laser techniques.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW a result of the very similar dimensions of these chemical components approximately one hundred% of Yb-doping may be realized. This one of a kind attribute permits ytterbium to go ahead and take put of yttrium with virtually no disruption towards the crystal’s lattice.
Adhesion Check Compliant with MIL-C-675C armed service benchmarks, an adhesion test concerned making use of a tape KYW Crystal that fulfills LT-90 requirements onto the lens film layer. The tape was affixed entirely after which you can eradicated vertically. This procedure was performed three times, resulting in no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical capabilities owing into the presence of thulium ions, and for that reason the elements could be further studied within the scope of laser and luminescence applications.
A higher brightnessQ-switched oscillator and regenerative amplifier according to a dual-crystal Yb:KGW laser
For tungstates, the ytterbium doping focus can be very substantial with out major quenching because the replaced ions have an exceedingly comparable ion radius, plus the inter-ion length is relatively huge.
Higher-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
