The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison with its counterpart Yb:KGW, is a amazing materials that plays a very important role in laser technological know-how. Its Most important perform would be to make ultrashort pulses of sunshine, spanning just some hundred femtoseconds.

The Yb:KYW crystal’s proficiency in mild absorption at about 981 nm will make the crystal like minded for diode pumping. It can be further more enhanced by its impressive performance in this method, coupled with its lower quantum defect.

The absorption and emission spectra of Yb:KYW Crystals Exhibit potent peaks at 980 nm and 1030 nm, respectively, ensuring productive Electrical power conversion and high efficiency in laser techniques.

Optical structure of a laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output in the radiation, WP is a 50 percent-wave plate, CL is really a collimating lens, FL check here is often a focusing lens, AE is really an active component created from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC could be the output mirror, and SAM is a semiconductor saturable-absorber mirror.

The monoclinic crystal buildings brings about a purely natural birefringence, assisting to keep away from thermally induced polarization rotation and depolarization decline.

Raman, luminescence and transmission spectra reveal optical capabilities owing to your existence of thulium ions, and therefore the supplies could possibly be even more analyzed from the scope of laser and luminescence apps.

Spatial framework on the beam plus the corresponding intensity profiles I on the output from the laser.

... Don't just the position of crystal from the cavity but also the amplification axis of crystal affects the laser Procedure enormously, as the absorption and emission cross sections of your crystal are quite unique according to the orientation on the crystal.

Li2WO4-WO3 flux was properly used decreasing the growth temperature underneath 900 oC. According to single crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
