The achieve bandwidth e.g. of Yb:KGW and Yb:KYW is incredibly huge when compared with that of Yb:YAG. This enables for wide wavelength tunability and for Substantially shorter pulse durations from manner-locked lasers. Values effectively below 100 fs happen to be accomplished with passive method locking.
This distinctive attribute of ultrafast pulses allows nonlinear optical conversation with tissue at minimal In general exposure, and drives programs for instance deep-tissue multiphoton microscopy and higher-precision eye medical procedures
We present a dual-crystal Yb:KGW laserthat iscapable to work to be a Q-switched oscillator with output energy around 24 W and pulse length of 20 ns,or as a regenerative amplifier with output electricity as much as 21 W and pulse duration down below two hundred fs immediately after compression of chirped pulses. Equally lasers have exceptional beam quality with beam parameter M2

This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by impressive linear arrays of semiconductor injection lasers owning fiber output. To circumvent spectral narrowing all through amplification plus the corresponding lengthening on the amplified pulse when it really is compressed, a mix of two Yb:KYW crystals ended up employed, with the spectral maxima with the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Just before the event of Nd:YAG, Nd3+:CaWO4 was a very important unusual-earth-doped laser attain medium. It was the truth is Employed in the very first continuously running crystal laser.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and so are applied as lasing materials to make ultrashort (~ one hundred-two hundred fs) substantial electric power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes running at 981 nm supports compact laser techniques.
Tungstates are inclined to acquire high Raman coefficients (�?Raman read more scattering). Consequently, they could generate major Raman get at average optical intensities. It is achievable to make use of the laser crystal by itself being a Raman converter.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW mainly because of the equivalent sizes of such chemical aspects as many as one hundred% of Yb-doping might be obtained.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared to its counterpart Yb:KGW, is a remarkable product that performs a significant position in laser know-how. Its Principal purpose is to create ultrashort pulses of light, spanning just a couple hundred femtoseconds.
