In sensible phrases, the Yb:KYW crystal has found its niche in high-energy laser apps resulting from its capacity to make large Vitality ultrashort laser pulses whilst maintaining a compact sizing. The interaction of its options �?seamless ytterbium substitution, potent absorption properties, ultrashort pulse generation and effectiveness in Power conversion �?positions the Yb:KYW crystal to be a cornerstone while in the laser engineering, masking various fields starting from scientific research to industrial apps.
The comparison with glasses is appropriate Considering that the substantial achieve bandwidth permits e.g. tungstate femtosecond lasers and tunable lasers to contend with glass lasers.
We current a dual-crystal Yb:KGW laserthat iscapable to work being a Q-switched oscillator with output electric power around 24 W and pulse length of twenty ns,or as being a regenerative amplifier with output ability as many as 21 W and pulse duration underneath 200 fs just after compression of chirped pulses. Both equally lasers have outstanding beam quality with beam parameter M2

By substituting yttrium with ytterbium from the crystal lattice of Yb:KYW because of get more info the equivalent measurements of those chemical aspects as many as a hundred% of Yb-doping can be achieved. This exclusive characteristic permits ytterbium to go ahead and take put of yttrium with pretty much no disruption into the crystal’s lattice.
Soon after air drying and subsequent cleansing using a cotton fabric soaked in Liquor, the movie surface showed no indications of peeling or scratches.
