The Yb:KYW crystal’s proficiency in light absorption at about 981 nm makes the crystal well suited for diode pumping. It really is further enhanced by its impressive efficiency in this process, coupled with its very low quantum defect.

Optical format of a laser with immediate pumping While using the radiation of semiconductor injection lasers. LD can be an IPG Photonics laser diode with fiber output from the radiation, WP is a 50 percent-wave plate, CL is a collimating lens, FL can be a concentrating lens, AE is undoubtedly an Energetic component made from an Yb:KYW crystal, DM is usually a spherical dichroic mirror, M1-M6 tend to be the cavity mirrors, OC would be the output mirror, and SAM is really a semiconductor saturable-absorber mirror.
Right after air drying and subsequent cleansing by using a cotton cloth soaked in Alcoholic beverages, the film area showed no indications of peeling or scratches.

Substantial-power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical programs
Though ytterbium-doped laser obtain media commonly show a little quantum defect, ytterbium-doped tungstates permit read more for notably smaller values. For example, a 1030-nm Yb:YAG laser would Usually be pumped about 940 nm, Whilst Yb:KGW or Yb:KYW might be most effectively pumped all-around 981 nm.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, can be a amazing substance that performs a significant purpose in laser technological know-how. Its Key perform is to make ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Simultaneously, a shorter laser wavelength could be obtained; it is possible to operate which has a quantum defect very well beneath one%. Being a consequence, the heat generation can be so compact this partly compensates the reduced thermal conductivity.
