In practical conditions, the Yb:KYW crystal has observed its area of interest in substantial-electricity laser programs because of its capacity to produce high Electricity ultrashort laser pulses even though sustaining a compact sizing. The interaction of its features �?seamless ytterbium substitution, robust absorption qualities, ultrashort pulse technology and efficiency in Power conversion �?positions the Yb:KYW crystal as a cornerstone during the laser technological innovation, masking numerous fields starting from scientific exploration to industrial apps.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is a amazing substance that performs an important purpose in laser technology. Its primary functionality would be to produce ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
We existing a twin-crystal Yb:KGW laserthat iscapable to work to be a Q-switched oscillator with output electricity approximately 24 W and pulse size of 20 ns,or as being a regenerative amplifier with output power around 21 W and pulse period below 200 fs soon after compression of chirped pulses. Each lasers have exceptional beam excellent with beam parameter M2
If you're seeking to obtain This page working with an nameless Private/Proxy network, be sure to disable that and take a look at accessing web page all over again.
Ultrafast lasers, with pulse widths of some picoseconds (10−12 s) or considerably less, permit enough time resolution expected in laser-psyched fluorescence lifetime spectroscopy and imaging strategies.Moreover, they produce significant pulse peak powers at superior repetition premiums and moderate typical output powers.
Before the development of Nd:YAG, Nd3+:CaWO4 was a vital unusual-earth-doped laser gain medium. It was in truth used in the 1st consistently working crystal laser.
Raman, luminescence and transmission spectra expose optical capabilities owing for here the presence of thulium ions, and as a consequence the resources might be further more studied inside the scope of laser and luminescence applications.
5 mm in addition to the center of your beam caustic. In an effort to Check out the manner matching simulation, we carried out the experiment with Ng-Slash crystal oscillator, which was produced Beforehand and in a very same ailment with simulation [11]. As demonstrated in Determine three(b) with crimson dots and line, the CW output electric power is highly dependent on the situation of laser crystal and the experimental end result coincides very well with simulation result. Like a Observe, multimode Procedure occurred in experiment once the dimensions of the pump beam is more substantial than TEM00 cavity method and it results in higher CW output electrical power while in the displacement area underneath three.five mm.
