In realistic conditions, the Yb:KYW crystal has discovered its market in large-electric power laser purposes resulting from its capacity to generate higher Power ultrashort laser pulses when maintaining a compact measurement. The interplay of its characteristics �?seamless ytterbium substitution, powerful absorption qualities, ultrashort pulse technology and performance in energy conversion �?positions the Yb:KYW crystal for a cornerstone from the laser technological know-how, masking varied fields ranging from scientific investigation to industrial programs.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared with its counterpart Yb:KGW, is actually a remarkable substance that performs an essential position in laser technology. Its Major functionality should be to produce ultrashort pulses of light, spanning just some hundred femtoseconds.
time. Crystals of your compound melts congruently at 1007 oC, nonetheless melt crystallization of top quality crystal is impossible because of period transition at ~920 oC. The very best seeded Answer system from
The absorption and emission spectra of Yb:KYW Crystals Display screen robust peaks at 980 nm and 1030 nm, respectively, guaranteeing effective Electricity conversion and high functionality in laser methods.
This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers getting fiber output. To circumvent spectral narrowing in the course of amplification plus the corresponding lengthening of your amplified pulse when it is compressed, a mix of two Yb:KYW crystals were utilized, With all the spectral maxima in the amplification shifted relative to each other and with spectral profiling from the amplified radiation.
Following air drying and subsequent cleansing by using a cotton cloth soaked in alcohol, the film surface area showed no indications of peeling or scratches.

five mm apart from the center on the beam caustic. In an effort to Look at the method matching simulation, we done the experiment with Ng-Slash crystal oscillator, which was made previously As well as in a similar situation with simulation [eleven]. As proven in Figure three(b) with red dots and line, the CW output electric power is very dependent on the place of laser crystal plus the experimental consequence coincides very well with simulation end result. Being a Take note, multimode operation happened in experiment when the dimension of your pump beam is larger sized than TEM00 cavity manner and it triggers bigger CW output electricity in the displacement region below 3.five mm.
For tungstates, the ytterbium doping concentration can be extremely superior with no major quenching since the replaced ions have a really comparable ion radius, along with the inter-ion distance is relatively large.
Higher-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical applications
