The Yb:KYW crystal’s proficiency in mild absorption at close to 981 nm will make the crystal well suited for diode pumping. It is actually even more Improved by its impressive efficiency in this process, coupled with its lower quantum defect.

The absorption and emission spectra of Yb:KYW Crystals Exhibit solid peaks at 980 nm and 1030 nm, respectively, making certain effective Electrical power conversion and superior overall performance in laser techniques.

Optical format of the laser with immediate pumping with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output of your radiation, WP is really a 50 %-wave plate, CL is usually a collimating lens, FL is actually a focusing lens, AE can be an active element created from an Yb:KYW crystal, DM is actually a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC will be the output mirror, and SAM is actually a semiconductor saturable-absorber mirror.

Adhesion Take a look at Compliant with MIL-C-675C army expectations, an adhesion exam involved applying a tape that meets LT-90 requirements on to the lens movie layer. The tape was affixed fully and after that taken out vertically. This technique was executed thrice, causing no blistering or peeling.

Raman, luminescence and transmission spectra reveal optical capabilities owing on the presence of thulium ions, and as a consequence the resources could possibly be further analyzed within the scope of laser and luminescence purposes.

For tungstates, the ytterbium doping concentration can be very large with no important quenching because the changed ions have a very identical ion radius, plus the inter-ion length is relatively big.

Higher-electric power repetitively pulsed ytterbium lasers with supershort pulse width and direct diode pumping for technological and biomedical purposes

The thermal conductivity of common double tungstates is of your get to 3–four W/(K m) �?which is not negative compared with other laser crystals (although many instances under for YAG), and fairly massive in contrast Using the thermal conductivity of typical Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison to its counterpart Yb:KGW, is really a amazing material that performs a crucial role in laser technological know-how. Its primary functionality is to crank out ultrashort pulses of sunshine, spanning just some hundred femtoseconds.
