We existing a dual-crystal Yb:KGW laserthat iscapable to work as a Q-switched oscillator with output electricity up to 24 W and pulse size of 20 ns,or being a regenerative amplifier with output power approximately 21 W and pulse period under 200 fs right after compression of chirped pulses. The two lasers have outstanding beam high-quality with beam parameter M2

Optical format of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output from the radiation, WP is usually a 50 percent-wave plate, CL is actually a collimating lens, FL is usually a focusing lens, AE can be an active aspect produced from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 would be the cavity mirrors, OC could be the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Immediately after air drying and subsequent cleaning with a cotton fabric soaked in Alcoholic beverages, the film floor confirmed no indications of peeling or scratches.

A high brightnessQ-switched oscillator and regenerative amplifier based upon a dual-crystal Yb:KGW laser
... at half-top were being produced within a master oscillator with selfsynchronization of your axial modes, explained in our before short article. 21 The new version of the laser, compared with that described in our previously post, made use of an Yb:KYW crystal by having an N pcut (optical axis N p on the index ellipsoid was parallel on the propagation direction with the laser radiation), Together with the polarization with the generated radiation directed together the N m axis.
Even so, once Nd3+:YAG grew to become commercially out there, the curiosity in CaWO4 dropped sharply. In later on decades, specific other tungstate crystals started to catch the attention of lots of consideration.

This tandem of attributes more info has significantly-achieving implications, particularly in the development of compact but powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at area temperature were being measured. The emission spectrum and life time with the three File 4 fired up condition were being determined. Utilizing common and modified Judd–Ofelt theories, the intensity parameters and the radiative lifetimes ended up calculated and fantastic settlement Along with the experimental effects was received for equally theories.
Inquire RP Photonics for any guidance regarding tungstate lasers, which includes femtosecond lasers and higher-electrical power lasers.
