The get bandwidth e.g. of Yb:KGW and Yb:KYW is extremely massive compared with that of Yb:YAG. This allows for vast wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values well below one hundred fs are obtained with passive manner locking.

This exceptional characteristic of ultrafast pulses permits nonlinear optical interaction with tissue at low Total exposure, and drives apps which include deep-tissue multiphoton microscopy and significant-precision eye medical procedures

We current a twin-crystal Yb:KGW laserthat iscapable to function for a Q-switched oscillator with output electric power nearly 24 W and pulse duration of twenty ns,or like a regenerative amplifier with output power as many as 21 W and pulse period underneath two hundred fs after compression of chirped pulses. Both lasers have excellent beam high-quality with beam parameter M2

The absorption and emission spectra of Yb:KYW Crystals Screen strong peaks at 980 nm and 1030 nm, respectively, making certain effective Electrical power conversion and superior effectiveness in laser programs.

This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by strong linear arrays of semiconductor injection lasers possessing fiber output. To stop spectral narrowing in the course of amplification and also the corresponding lengthening of the amplified pulse when it is actually compressed, a mix of two Yb:KYW crystals had been made use of, While using the spectral maxima on the amplification shifted relative to each other and with spectral profiling with the amplified radiation.

In advance of the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser acquire medium. It had been in fact used in the 1st continuously working crystal laser.

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

Though ytterbium-doped laser attain media frequently show a small quantum defect, ytterbium-doped tungstates permit for specifically tiny values. As an example, a 1030-nm Yb:YAG laser would Typically be pumped about 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most proficiently pumped about 981 nm.

This tandem of characteristics has considerably-reaching implications, specially in the construction of compact nevertheless powerfull lasers.
