The gain bandwidth e.g. of Yb:KGW and Yb:KYW is very huge in comparison with that of Yb:YAG. This allows for broad wavelength tunability and for Considerably shorter pulse durations from manner-locked lasers. Values well below a hundred fs have already been reached with passive mode locking.
The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, can be a extraordinary material that plays an important purpose in laser know-how. Its Principal operate is usually to crank out ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
We existing a twin-crystal Yb:KGW laserthat iscapable to function being a Q-switched oscillator with output power approximately 24 W and pulse duration of twenty ns,or being a regenerative amplifier with output electric power as much as 21 W and pulse length under two hundred fs following compression of chirped pulses. The two lasers have great beam high quality with beam parameter M2
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, making sure efficient Power conversion and high functionality in laser systems.
Optical structure of a laser with direct pumping With all the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output on the radiation, WP is often a 50 percent-wave plate, CL can be a collimating lens, FL can be a focusing lens, AE is an Lively factor produced from an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC could be the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.
Immediately after air drying and subsequent cleansing by using a cotton cloth soaked in website alcohol, the movie floor showed no indications of peeling or scratches.
FIG. 1. Optical structure of a laser with direct pumping Along with the radiation of semiconductor injection lasers. LD is definitely an IPG Photonics laser diode with fiber output
Tungstates are inclined to obtain superior Raman coefficients (�?Raman scattering). Therefore, they can crank out considerable Raman obtain at average optical intensities. It is achievable to utilize the laser crystal itself like a Raman converter.
... at 50 percent-top were being created in a learn oscillator with selfsynchronization of the axial modes, explained inside our before posting. 21 The new edition of your laser, compared with that explained within our earlier post, used an Yb:KYW crystal having an N pcut (optical axis N p of your index ellipsoid was parallel to your propagation route in the laser radiation), With all the polarization from the created radiation directed alongside the N m axis.
High-ability repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
Though ytterbium-doped laser achieve media usually show a little quantum defect, ytterbium-doped tungstates let for particularly tiny values. As an example, a 1030-nm Yb:YAG laser would Typically be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW could possibly be most competently pumped about 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared with its counterpart Yb:KGW, is usually a exceptional substance that performs an important part in laser know-how. Its Key functionality would be to create ultrashort pulses of light, spanning just a few hundred femtoseconds.
