The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, when compared to its counterpart Yb:KGW, is a exceptional content that plays a vital position in laser know-how. Its Most important functionality should be to make ultrashort pulses of light, spanning only a few hundred femtoseconds.
Femtosecond laser based upon Yb:KYW crystals with suppression of spectral narrowing inside a regenerative amplifier by spectral profiling of the heart beat
The absorption and emission spectra of Yb:KYW Crystals Show strong peaks at 980 nm and 1030 nm, respectively, ensuring efficient Strength conversion and significant overall performance in laser devices.
Optical format of the laser with immediate pumping While using the radiation of semiconductor injection lasers. LD is surely an IPG Photonics laser diode with fiber output of the radiation, WP is really a 50 percent-wave plate, CL is really a collimating lens, FL can be a concentrating lens, AE is an active ingredient comprised of an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC could be the output mirror, and SAM is a semiconductor saturable-absorber mirror.
Adhesion Test Compliant with MIL-C-675C navy benchmarks, an adhesion test involved applying a tape that meets LT-ninety specifications on to the lens movie layer. The tape was affixed thoroughly after which you can removed vertically. This procedure was executed 3 times, leading to no blistering or peeling.
Raman, luminescence and transmission spectra reveal optical characteristics owing to your existence of thulium ions, and as a consequence the materials might be additional studied within the scope of laser and luminescence applications.
A higher brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser

Higher-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
Although ytterbium-doped laser obtain media usually show a small quantum defect, ytterbium-doped read more tungstates let for significantly compact values. By way of example, a 1030-nm Yb:YAG laser would normally be pumped around 940 nm, whereas Yb:KGW or Yb:KYW may very well be most effectively pumped about 981 nm.

Simultaneously, a shorter laser wavelength could be attained; it is feasible to work by using a quantum defect nicely down below 1%. To be a consequence, the heat technology may be so compact that this partly compensates the decreased thermal conductivity.
