The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is usually a extraordinary substance that plays a vital purpose in laser know-how. Its Principal operate would be to make ultrashort pulses of light, spanning just some hundred femtoseconds.

LD is an IPG Photonics laser diode with fiber output of your radiation, WP is really a half-wave plate, CL is usually a collimating lens, FL can be a focusing lens, AE is an Energetic factor made from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are classified as the cavity mirrors, OC is definitely the output mirror, and SAM is often a semiconductor saturable-absorber mirror.

Adhesion Take a look at Compliant with MIL-C-675C armed service standards, an adhesion examination concerned implementing a tape that meets LT-90 requirements on to the lens film layer. The tape was affixed completely after which taken out vertically. This procedure was executed thrice, causing no blistering or peeling.

For tungstates, the ytterbium doping focus can be very significant without the need of major quenching since the changed ions have an incredibly identical ion radius, plus the inter-ion distance is relatively substantial.

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

When ytterbium-doped laser achieve media typically show a small quantum defect, ytterbium-doped tungstates let for particularly little values. For example, a 1030-nm Yb:YAG laser would Typically be pumped all-around 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most effectively pumped close to 981 nm.
