The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is really a exceptional content that performs a significant purpose in laser technology. Its primary function is to generate ultrashort pulses of sunshine, spanning just some hundred femtoseconds.

The Yb:KYW crystal’s proficiency in light absorption at all-around 981 nm tends to make the crystal compatible for diode pumping. It is actually further enhanced by its outstanding efficiency in this process, coupled with its minimal quantum defect.

Optical layout of a laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output with the radiation, WP is a fifty percent-wave plate, CL is actually a collimating lens, FL is usually a concentrating lens, AE is an Energetic ingredient created from an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 will be the cavity mirrors, OC is definitely the output mirror, and SAM is really a semiconductor saturable-absorber mirror.

Adhesion Examination Compliant with MIL-C-675C military services requirements, an adhesion check involved applying a tape that meets LT-90 specifications onto the lens film layer. The tape was affixed totally after which taken out vertically. This treatment was done three click here times, resulting in no blistering or peeling.

Raman, luminescence and transmission spectra expose optical features owing for the presence of thulium ions, and so the components may very well be further more examined during the scope of laser and luminescence purposes.

Spatial composition with the beam plus the corresponding depth profiles I on the output in the laser.

For tungstates, the ytterbium doping concentration can be quite large without important quenching as the replaced ions have an incredibly identical ion radius, as well as the inter-ion length is pretty large.

By substituting yttrium with ytterbium in the crystal lattice of Yb:KYW as a result of similar measurements of these chemical components approximately one hundred% of Yb-doping may be accomplished.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is a remarkable material that performs a very important purpose in laser technological know-how. Its Most important purpose is usually to create ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.

Talk to RP Photonics for almost any guidance about tungstate lasers, like femtosecond lasers and higher-electric power lasers.
