This special attribute of ultrafast pulses permits nonlinear optical interaction with tissue at small All round exposure, and drives programs which include deep-tissue multiphoton microscopy and large-precision eye surgery
The Yb:KYW crystal’s proficiency in gentle absorption at all over 981 nm can make the crystal like minded for diode pumping. It is more Improved by its impressive effectiveness in this process, coupled with its lower quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Screen strong peaks at 980 nm and 1030 nm, respectively, ensuring economical Power conversion and significant effectiveness in laser techniques.
This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers acquiring fiber output. To avoid spectral narrowing throughout amplification plus the corresponding lengthening on the amplified pulse when it is compressed, a mix of two Yb:KYW crystals were applied, With all the spectral maxima of the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
Soon after air drying and subsequent cleaning that has a cotton cloth soaked in Alcoholic beverages, the film floor confirmed no signs of peeling or scratches.
FIG. 1. Optical structure of the laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output
Tungstates are likely to possess large Raman coefficients (�?Raman scattering). Thus, they can produce considerable Raman get at moderate optical intensities. It is feasible to make use of the laser crystal by itself like a Raman converter.
... at 50 percent-peak have been produced in the learn oscillator with selfsynchronization from the axial modes, described inside our before posting. 21 The new edition in the laser, compared with that explained within our before post, applied an Yb:KYW crystal with an N pcut (optical axis N p of the index ellipsoid was parallel towards the propagation way in the laser radiation), Together with click here the polarization of your generated radiation directed together the N m axis.
High-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, can be a outstanding product that performs a very important function in laser technological innovation. Its Key operate will be to create ultrashort pulses of light, spanning only a few hundred femtoseconds.
