We existing a twin-crystal Yb:KGW laserthat iscapable to work for a Q-switched oscillator with output ability up to 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electric power as much as 21 W and pulse duration below two hundred fs immediately after compression of chirped pulses. Both equally lasers have great beam good quality with beam parameter M2
Coloration-coded reflectivity of the Bragg mirror being a functionality of wavelength and angle of the incident beam.
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 having fiber output. To circumvent spectral narrowing all through amplification as well as corresponding lengthening on the amplified pulse when it really is compressed, a mix of two Yb:KYW crystals have been utilized, While using the spectral maxima on the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Ahead of the event of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser gain medium. It was the truth is Employed in the very first continually running crystal laser.
Raman, luminescence and transmission spectra reveal optical functions owing on the presence of thulium ions, and as a consequence the supplies can be additional researched inside the scope of laser and luminescence programs.

However, when Nd3+:YAG grew to become commercially out there, the interest in CaWO4 dropped sharply. In later yrs, sure other tungstate crystals began to entice plenty of awareness.
Though ytterbium-doped laser gain media generally exhibit a little quantum defect, ytterbium-doped tungstates allow for for significantly small values. For example, a 1030-nm Yb:YAG laser would Commonly be pumped all over 940 nm, While Yb:KGW or Yb:KYW may be most effectively pumped about 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is often a amazing content that plays an essential job in laser technological know-how. Its Key functionality should be to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.
Inquire RP Photonics for click here almost any assistance concerning tungstate lasers, which include femtosecond lasers and higher-electric power lasers.
