The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, in comparison to its counterpart Yb:KGW, is actually a impressive materials that performs a vital role in laser technological know-how. Its Principal functionality should be to deliver ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
We existing a twin-crystal Yb:KGW laserthat iscapable to operate like a Q-switched oscillator with output electric power nearly 24 W and pulse duration of twenty ns,or as a regenerative amplifier with output energy around 21 W and pulse length underneath 200 fs after compression of chirped pulses. Each lasers have excellent beam high-quality with beam parameter M2

Optical structure of a laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is really an IPG Photonics laser diode with fiber output in the radiation, WP can be a half-wave plate, CL is really a collimating lens, FL is a focusing lens, AE can be an active aspect produced from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC would be the output mirror, and SAM is usually a semiconductor saturable-absorber mirror.
Adhesion Take a look at Compliant with MIL-C-675C military requirements, an adhesion examination included making use of a tape that fulfills LT-ninety requirements onto the lens movie layer. The tape was affixed totally then removed vertically. This procedure was executed thrice, causing no blistering or peeling.

Tungstates tend to possess large Raman coefficients (�?Raman scattering). Thus, they might generate important Raman get at reasonable optical intensities. It is achievable to make use of the laser crystal itself as being a Raman converter.
For tungstates, the ytterbium doping concentration can be quite substantial with no significant quenching because the replaced ions have an exceedingly equivalent ion radius, plus the inter-ion length is relatively big.
... Not merely the situation of crystal from the cavity and also the amplification axis of crystal has an effect on the laser Procedure considerably, since the absorption and emission cross sections with the crystal are rather unique in accordance with the orientation with the crystal.
The thermal conductivity of widespread double tungstates is in the get to 3–four W/(K m) �?which is not terrible in contrast with other laser crystals (Even though various occasions a lot less than for YAG), and pretty substantial compared Together with the thermal conductivity of typical glasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) as compared here to its counterpart Yb:KGW, can be a extraordinary substance that performs an essential function in laser engineering. Its Main function is to deliver ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.
Check with RP Photonics for just about any advice relating to tungstate lasers, such as femtosecond lasers and large-ability lasers.
