In functional phrases, the Yb:KYW crystal has uncovered its niche in higher-ability laser purposes due to its power to deliver significant Electricity ultrashort laser pulses even though keeping a compact dimension. The interaction of its capabilities �?seamless ytterbium substitution, powerful absorption properties, ultrashort pulse era and efficiency in Vitality conversion �?positions the Yb:KYW crystal as being a cornerstone within the laser engineering, covering numerous fields ranging from scientific investigate to industrial purposes.
This exceptional attribute of ultrafast pulses permits nonlinear optical interaction with tissue at lower In general exposure, and drives programs which include deep-tissue multiphoton microscopy and large-precision eye surgical procedures
We present a dual-crystal Yb:KGW laserthat iscapable to operate as a Q-switched oscillator with output energy up to 24 W and pulse length of twenty ns,or to be a regenerative amplifier with output power up to 21 W and pulse period underneath 200 fs soon after compression of chirped pulses. The two lasers have superb beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show strong peaks at 980 nm and 1030 nm, respectively, making certain productive Strength conversion and substantial general performance in laser units.
By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW due to the equivalent measurements of those chemical aspects as many as one hundred% of Yb-doping could be accomplished. This one of a kind attribute permits ytterbium to go ahead and take position of yttrium with just about no disruption to your crystal’s lattice.
Right after air drying and subsequent cleansing having a cotton fabric soaked in Alcoholic beverages, the film floor confirmed no signs of peeling or scratches.

... Not just the position of crystal within the cavity but also the amplification axis of crystal has an effect on the laser Procedure tremendously, because the absorption and emission cross sections of your crystal are rather distinctive based on the orientation from the crystal.
On account of previously detected malicious actions which originated within the network you might be making use of, be sure to request unblock to web-site.
This tandem of attributes has significantly-achieving implications, particularly in the construction of compact but powerfull lasers.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison KYW Crystal to its counterpart Yb:KGW, is really a exceptional content that performs a significant part in laser engineering. Its primary purpose is always to deliver ultrashort pulses of light, spanning just some hundred femtoseconds.
