In useful conditions, the Yb:KYW crystal has discovered its specialized niche in substantial-energy laser programs due to its capability to generate substantial Vitality ultrashort laser pulses though retaining a compact dimensions. The interplay of its characteristics �?seamless ytterbium substitution, strong absorption attributes, ultrashort pulse era and effectiveness in Vitality conversion �?positions the Yb:KYW crystal as being a cornerstone from the laser technological know-how, masking varied fields starting from scientific study to industrial purposes.
This one of a kind attribute of ultrafast pulses permits nonlinear optical conversation with tissue at low Total exposure, and drives applications which include deep-tissue multiphoton microscopy and significant-precision eye surgical treatment
We present a twin-crystal Yb:KGW laserthat iscapable to function as a Q-switched oscillator with output electrical power as much as 24 W and pulse duration of 20 ns,or as being a regenerative amplifier with output electric power up to 21 W and pulse length beneath 200 fs right after compression of chirped pulses. Both lasers have excellent beam quality with beam parameter M2
Color-coded reflectivity of the Bragg mirror for a function of wavelength and angle from the incident beam.
This paper describes a femtosecond laser regenerative amplifier determined by two Yb:KYW crystals with direct longitudinal pumping by effective linear arrays of semiconductor injection lasers acquiring fiber output. To forestall spectral narrowing through amplification as well as corresponding lengthening on the amplified pulse when it really is compressed, a combination of two Yb:KYW crystals were being applied, While using the spectral maxima on the amplification shifted relative to each other and with spectral profiling from the amplified radiation.
The monoclinic crystal constructions brings about a purely natural birefringence, assisting to steer clear of thermally induced polarization rotation and depolarization loss.
FIG. one. Optical format of the laser with direct pumping Together with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
Spatial structure with the beam and the corresponding intensity profiles I for the read more output from the laser.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW a result of the very similar dimensions of those chemical features as much as 100% of Yb-doping might be attained.
