In functional terms, the Yb:KYW crystal has uncovered its area of interest in higher-energy laser programs as a result of its capability to generate higher Vitality ultrashort laser pulses even though preserving a compact dimension. The interplay of its attributes �?seamless ytterbium substitution, solid absorption properties, ultrashort pulse technology and efficiency in Strength conversion �?positions the Yb:KYW crystal like a cornerstone inside the laser engineering, covering varied fields ranging from scientific analysis to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a amazing material that plays an important part in laser technological know-how. Its Key functionality should be to crank out ultrashort pulses of light, spanning just a couple hundred femtoseconds.
We current a dual-crystal Yb:KGW laserthat iscapable to function as being a Q-switched oscillator with output electric power approximately 24 W and pulse size of twenty ns,or as a regenerative amplifier with output energy nearly 21 W and pulse length under 200 fs soon after compression of chirped pulses. Equally lasers have fantastic beam top quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with immediate longitudinal pumping by potent linear arrays of semiconductor injection lasers owning fiber output. To circumvent spectral narrowing for the duration of amplification as well as the corresponding lengthening with the amplified pulse when it can be compressed, a combination of two Yb:KYW crystals ended up applied, Using the spectral maxima of your amplification shifted relative to one another and KYW Crystal with spectral profiling with the amplified radiation.
Following air drying and subsequent cleaning using a cotton fabric soaked in alcohol, the movie surface showed no signs of peeling or scratches.

Nonetheless, once Nd3+:YAG became commercially out there, the interest in CaWO4 dropped sharply. In afterwards years, selected other tungstate crystals started to appeal to lots of focus.
Resulting from previously detected malicious habits which originated from the network you are utilizing, remember to request unblock to web site.
Li2WO4-WO3 flux was properly utilized decreasing the growth temperature underneath 900 oC. As outlined by solitary crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
