In functional phrases, the Yb:KYW crystal has located its market in large-electric power laser purposes resulting from its power to generate high energy ultrashort laser pulses whilst sustaining a compact size. The interaction of its features �?seamless ytterbium substitution, strong absorption characteristics, ultrashort pulse technology and performance in Electricity conversion �?positions the Yb:KYW crystal being a cornerstone while in the laser know-how, covering numerous fields ranging from scientific study to industrial apps.

The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a remarkable material that plays a crucial position in laser technology. Its Main purpose is always to generate ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.

time. Crystals on the compound melts congruently at 1007 oC, nonetheless melt crystallization of top of the range crystal is difficult resulting from phase changeover at ~920 oC. The highest seeded Option approach from

FIG. four. Autocorrelation operate of the heart beat 共a兲and spectrum 共b兲of a laser with an oblong Lively factor for an output energy of seven hundred mW. The width of

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by potent linear arrays of semiconductor injection lasers owning fiber output. To avoid spectral narrowing throughout amplification as well as corresponding lengthening in the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals ended up used, Together with the spectral maxima from the amplification shifted relative to one another and with spectral profiling from the amplified radiation.

Ahead of the event of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser attain medium. It absolutely was in fact used in the very first constantly working crystal laser.

Raman, luminescence and transmission spectra expose optical options owing towards the presence of thulium ions, and for that reason the products could be additional studied while in the scope of laser and luminescence apps.

5 mm aside from the center of the beam caustic. In order to check the manner matching simulation, we carried out the experiment with Ng-Reduce crystal oscillator, which was developed Earlier and in a same affliction with simulation [11]. read more As shown in Figure 3(b) with purple dots and line, the CW output electricity is highly dependent on the placement of laser crystal and also the experimental final result coincides properly with simulation result. Being a note, multimode operation transpired in experiment in the event the dimension with the pump beam is bigger than TEM00 cavity manner and it leads to better CW output power inside the displacement area underneath three.five mm.

EKSMA Optics takes advantage of cookies to provde the most effective searching practical experience. When you keep on to utilize our solutions, We're going to suppose that you simply conform to the use of these types of cookies.

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

There won't be any merchandise in your cart. Increase items to the cart and request an Formal estimate or order on line Subtotal

This tandem of attributes has significantly-achieving implications, particularly in the development of compact yet powerfull lasers.

The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)two) crystal at space temperature have been calculated. The emission spectrum and life span of your 3 File 4 psyched point out were determined. Making use of common and modified Judd–Ofelt theories, the intensity parameters along with the radiative lifetimes ended up calculated and fantastic arrangement Along with the experimental effects was received for the two theories.

Inquire RP Photonics for almost any guidance relating to tungstate lasers, such as femtosecond lasers and significant-energy lasers.
