We current a dual-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electricity approximately 24 W and pulse duration of twenty ns,or to be a regenerative amplifier with output ability nearly 21 W and pulse period under 200 fs following compression of chirped pulses. Both lasers have fantastic beam high-quality with beam parameter M2
FIG. four. Autocorrelation operate of the heart beat 共a兲and spectrum 共b兲of a laser with an oblong Lively component for an output ability of 700 mW. The width of
By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW due to the very similar sizes of these chemical features approximately a hundred% of Yb-doping can be attained. This exceptional characteristic permits ytterbium to take the position of yttrium with almost no disruption into the crystal’s lattice.
The monoclinic crystal structures ends in a organic birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.
By publishing the knowledge, you give your consent to the probable publication of one's inputs on our Web page Based on our regulations. (For those who later retract your consent, We'll delete All those inputs.) As your inputs are first reviewed through the writer, They might be released with a few hold off.
Tungstates are inclined to acquire superior Raman coefficients (�?Raman scattering). Therefore, they're able to create major Raman attain at average optical intensities. It is achievable to make use of the laser crystal itself as being a Raman converter.
... at 50 percent-height were created in the grasp oscillator with selfsynchronization from the axial modes, described in our previously post. 21 The new edition on the laser, as opposed to that explained in our previously post, made use of an Yb:KYW crystal using an N pcut (optical axis N p from the index ellipsoid was parallel to your propagation path with the laser radiation), With all the polarization of your generated radiation directed alongside the N m axis.
... Not simply the situation of crystal during the cavity but will also the amplification axis of crystal has an effect on the laser Procedure considerably, since the absorption and emission cross sections on the crystal are really unique based on the orientation in the crystal.
