The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a impressive materials that plays a crucial position in laser technological know-how. Its Most important function is to generate ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heartbeat

The absorption and emission spectra of Yb:KYW Crystals Display screen strong peaks at 980 nm and 1030 nm, respectively, ensuring effective Vitality conversion and significant general performance in laser systems.

Optical format of the laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output of your radiation, WP is often a fifty percent-wave plate, CL is usually a collimating lens, FL is actually a concentrating lens, AE is surely an Lively element constructed from an Yb:KYW crystal, DM can be 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.

The monoclinic crystal structures results in a natural birefringence, helping to steer clear of thermally induced polarization rotation and depolarization loss.

Raman, luminescence and transmission spectra reveal optical functions owing towards the existence of thulium ions, and as a consequence the materials might be additional studied within the scope of laser and luminescence applications.

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

The thermal conductivity of popular double tungstates is on the order to 3–four W/(K m) �?which is not lousy in comparison with other laser crystals (although various occasions lower than for YAG), and quite massive as opposed With all the thermal conductivity of usual glasses.

Simultaneously, a shorter laser wavelength check here could be attained; it is feasible to operate that has a quantum defect effectively below one%. To be a consequence, the heat technology could be so small that this partly compensates the lessen thermal conductivity.
