The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is a amazing product that performs a very important role in laser technologies. Its Major perform is always to produce ultrashort pulses of light, spanning just some hundred femtoseconds.
We present a dual-crystal Yb:KGW laserthat iscapable to work as a Q-switched oscillator with output energy around 24 W and pulse size of 20 ns,or as being a regenerative amplifier with output electricity approximately 21 W and pulse period underneath 200 fs soon after compression of chirped pulses. The two lasers have outstanding beam high quality with beam parameter M2
Shade-coded reflectivity of the Bragg mirror as being a function of wavelength and angle with the incident beam.
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW as a result of related measurements of those chemical things approximately one hundred% of Yb-doping may very well be obtained. This unique attribute permits ytterbium to go ahead and take position of yttrium with pretty much no disruption towards the crystal’s lattice.
Right after air drying and subsequent cleaning with a cotton cloth soaked in Alcoholic beverages, the film surface area confirmed no indications of peeling or scratches.

Substantial-energy repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications
While ytterbium-doped laser obtain media generally exhibit a small quantum defect, ytterbium-doped tungstates enable for specially compact values. For instance, a 1030-nm Yb:YAG laser would Typically be pumped all around 940 nm, While Yb:KGW or Yb:KYW may be most proficiently pumped all around 981 nm.
