In functional conditions, the Yb:KYW crystal has discovered its area of interest in substantial-electric power laser purposes due to its ability to deliver substantial Power ultrashort laser pulses although maintaining a compact measurement. The interaction of its functions �?seamless ytterbium substitution, robust absorption traits, ultrashort pulse technology and efficiency in energy conversion �?positions the Yb:KYW crystal for a cornerstone inside the laser technologies, covering varied fields ranging from scientific investigation to industrial applications.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is really a impressive substance that plays a crucial part in laser know-how. Its Key purpose will be to crank out ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
We current a dual-crystal Yb:KGW laserthat iscapable to operate as being a Q-switched oscillator with output electrical power up to 24 W and pulse length of twenty ns,or to be a regenerative amplifier with output power as much as 21 W and pulse duration beneath two hundred fs just after compression of chirped pulses. Both of those lasers have fantastic beam excellent with beam parameter M2
In case you are seeking to entry this site making use of an nameless Non-public/Proxy community, make sure you disable that and try accessing web site yet again.
Ultrafast lasers, with pulse widths of some picoseconds (ten−twelve s) or a lot less, empower enough time resolution necessary in laser-psyched fluorescence life span spectroscopy and imaging approaches.Also, they provide higher pulse peak powers at superior repetition premiums and reasonable average output powers.
In advance of the event of Nd:YAG, Nd3+:CaWO4 was a vital exceptional-earth-doped laser achieve medium. It had been in fact Utilized in the main repeatedly running crystal laser.

Spatial construction of the beam and also the corresponding depth profiles I in the output on the laser.
For tungstates, the ytterbium doping concentration can be extremely high without major quenching as the changed ions have a really equivalent ion radius, as well as the inter-ion distance is relatively massive.
Large-power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps
While ytterbium-doped laser obtain media normally show a small quantum defect, ytterbium-doped tungstates let for significantly small values. Such as, a 1030-nm Yb:YAG laser would Usually be pumped about 940 nm, whereas Yb:KGW or Yb:KYW could be most competently pumped all-around 981 nm.
Li2WO4-WO3 flux was productively used decreasing the growth temperature below 900 oC. In line with one crystal x-ray measurements, the crystal corresponds to the P2/n Area group.
