The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a amazing product that plays a very important purpose in laser technological innovation. Its Major purpose is to make ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

We existing a dual-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output electrical power around 24 W and pulse length of twenty ns,or as being a regenerative amplifier with output power up to 21 W and pulse length beneath two hundred fs following compression of chirped pulses. The two lasers have excellent beam high-quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with immediate longitudinal pumping by potent linear arrays of semiconductor injection lasers acquiring fiber output. To prevent spectral narrowing throughout amplification plus the corresponding lengthening of your amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals were being made use of, with the spectral maxima from the amplification shifted relative to each other and with spectral profiling of your amplified radiation.

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

Tungstates have a tendency to own high Raman coefficients (�?Raman scattering). Therefore, they can deliver considerable Raman achieve at average optical intensities. It can be done to use the laser crystal by itself for a Raman converter.
