The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, compared to its counterpart Yb:KGW, is actually a impressive substance that performs a significant job in laser technologies. Its Main perform would be to produce ultrashort pulses of light, spanning just some hundred femtoseconds.
We current a dual-crystal Yb:KGW laserthat iscapable to work as being a Q-switched oscillator with output ability up to 24 W and pulse duration of 20 ns,or as a regenerative amplifier with output ability up to 21 W and pulse period beneath two hundred fs soon after compression of chirped pulses. Both equally lasers have exceptional beam top quality with beam parameter M2
Color-coded reflectivity of a Bragg mirror being a functionality of wavelength and angle of the incident beam.
Optical structure of a laser with immediate pumping Together with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output from the radiation, WP is usually a 50 %-wave plate, CL is actually a collimating lens, FL is a focusing lens, AE can be an active aspect made 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 Check Compliant with MIL-C-675C armed service benchmarks, an adhesion test involved applying a tape that meets LT-90 specifications on to the lens movie layer. The tape was affixed entirely and then removed vertically. This process was performed thrice, causing no blistering or peeling.

... Not just the posture of crystal in the cavity but additionally the amplification axis of crystal affects the laser operation greatly, as the absorption and emission cross sections of your crystal are pretty distinctive in accordance with the orientation on the crystal.
The thermal conductivity of widespread double tungstates is from the get to 3–four W/(K m) �?which is not undesirable in contrast with other laser crystals (Whilst numerous situations under for YAG), and quite huge as opposed Using the thermal conductivity of regular Eyeglasses.
Li2WO4-WO3 flux was effectively utilized cutting down The expansion temperature below 900 oC. In line with click here solitary crystal x-ray measurements, the crystal corresponds into the P2/n space group.
Yb:KYW crystal (Yb-doped potassium yttrium tungstate) compared to its counterpart Yb:KGW, is really a outstanding material that performs a significant position in laser technological innovation. Its Major function is to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.
Ask RP Photonics for virtually any assistance regarding tungstate lasers, together with femtosecond lasers and substantial-power lasers.
