The Yb:KYW crystal’s proficiency in gentle absorption at all around 981 nm will make the crystal like minded for diode pumping. It truly is further more enhanced by its exceptional effectiveness in this process, coupled with its lower quantum defect.

For anyone who is attempting to accessibility This great site making use of an nameless Non-public/Proxy community, make sure you disable that and check out accessing web page once more.

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by impressive linear arrays of semiconductor injection lasers owning fiber output. To forestall spectral narrowing through amplification plus the corresponding lengthening on the amplified pulse when it truly is compressed, a combination of two Yb:KYW crystals were being employed, Using the spectral maxima of your amplification shifted relative to each other and with spectral profiling of the amplified radiation.

Immediately after air drying and subsequent cleaning which has a cotton cloth soaked in Liquor, the movie surface area confirmed no indications of peeling or scratches.

PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are used as lasing materials to crank out ultrashort (~ 100-two hundred fs) large electric power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser programs.

5 mm apart from the middle with the beam caustic. So that you can Test the method matching simulation, we performed the experiment with Ng-cut crystal oscillator, which was made Earlier and in a identical ailment with simulation [eleven]. As shown in Determine three(b) with crimson dots and line, the CW output power is highly depending on the place of laser crystal as well as experimental consequence coincides nicely with simulation final result. Like a Take note, multimode operation transpired in experiment in the event the dimension of the pump beam is more substantial than TEM00 cavity manner and it leads to better CW output power inside the displacement area down below three.5 mm.

For tungstates, the ytterbium doping concentration can be extremely higher without the need of considerable quenching as the replaced ions have an exceptionally comparable ion radius, as well as the inter-ion length is pretty large.

Substantial-energy repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical apps

In this article you can post queries and remarks. As far as they get approved with the writer, they will appear earlier mentioned this paragraph together with the author’s response. The creator will decide on acceptance depending KYW Crystal on selected conditions. Essentially, the issue has to be of sufficiently broad curiosity.
