The Yb:KYW crystal’s proficiency in gentle absorption at all over 981 nm makes the crystal well matched for diode pumping. It is more Improved by its outstanding effectiveness in this process, coupled with its small quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Show sturdy peaks at 980 nm and 1030 nm, respectively, making certain efficient Electrical power conversion and substantial efficiency in laser methods.
Optical layout of a laser with direct pumping with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output in the radiation, WP is a fifty percent-wave plate, CL is really a collimating lens, FL is often a focusing lens, AE is undoubtedly an Energetic element created from an Yb:KYW crystal, DM is really a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC would be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.
Adhesion Take a look at Compliant with read more MIL-C-675C military benchmarks, an adhesion exam involved applying a tape that satisfies LT-90 requirements on to the lens movie layer. The tape was affixed completely and after that taken off vertically. This method was carried out three times, leading to no blistering or peeling.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are made use of as lasing materials to create ultrashort (~ 100-two hundred fs) superior electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser techniques.
A superior brightnessQ-switched oscillator and regenerative amplifier based upon a dual-crystal Yb:KGW laser
... at half-height ended up generated inside a master oscillator with selfsynchronization from the axial modes, explained inside our before short article. 21 The new edition on the laser, unlike that described in our before write-up, made use of an Yb:KYW crystal by having an N pcut (optical axis N p with the index ellipsoid was parallel for the propagation course with the laser radiation), While using the polarization on the created radiation directed alongside the N m axis.
By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW a result of the very similar dimensions of such chemical elements approximately a hundred% of Yb-doping may very well be obtained.

This tandem of attributes has far-reaching implications, specially in the development of compact nonetheless powerfull lasers.
The polarized absorption spectra of Tm3+-doped potassium yttrium tungstate (Tm:KY(WO4)2) crystal at room temperature had been calculated. The emission spectrum and lifetime in the three F four enthusiastic condition had been established. Applying standard and modified Judd–Ofelt theories, the depth parameters and also the radiative lifetimes were being calculated and very good arrangement with the experimental final results was obtained for both theories.
