The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is actually a amazing material that performs an important role in laser know-how. Its primary operate is usually to crank out ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

The Yb:KYW crystal’s proficiency in mild absorption at all around 981 nm can make the crystal well suited for diode pumping. It truly is further more Increased by its exceptional performance in this process, coupled with its reduced quantum defect.

Shade-coded reflectivity of the Bragg mirror as a function of wavelength and angle in the incident beam.

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

In advance of the development of Nd:YAG, Nd3+:CaWO4 was an important rare-earth-doped laser achieve medium. It was actually Utilized in the main constantly running crystal laser.

(If you later retract your consent, We are going to delete Those people inputs.) As your inputs are initial reviewed with the creator, They could be printed with a few delay.

Tungstates are likely to have large Raman coefficients (�?Raman scattering). Thus, they can create substantial Raman acquire at moderate optical intensities. It is possible to use the laser crystal itself as being a Raman converter.

By substituting yttrium with ytterbium while in the crystal read more lattice of Yb:KYW a result of the equivalent sizes of those chemical factors up to a hundred% of Yb-doping may be accomplished.
