The Yb:KYW crystal’s proficiency in gentle absorption at all over 981 nm would make the crystal compatible for diode pumping. It truly is more enhanced by its remarkable effectiveness in this process, coupled with its reduced quantum defect.

Shade-coded reflectivity of a Bragg mirror as a function of wavelength and angle of your incident beam.

Optical structure of the laser with immediate pumping Along 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 fifty percent-wave plate, CL is usually a collimating lens, FL can be a concentrating lens, AE is surely an Lively element produced from an Yb:KYW crystal, DM is often a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC may be the output mirror, and SAM is often a semiconductor saturable-absorber mirror.

The monoclinic crystal buildings ends in a purely natural birefringence, assisting to keep away from thermally induced polarization rotation and depolarization reduction.

Raman, luminescence and transmission spectra expose optical attributes owing on the existence of thulium ions, and so the elements may very well be additional examined within the scope of laser and luminescence purposes.

A high brightnessQ-switched oscillator and regenerative amplifier based on a twin-crystal Yb:KGW laser

High-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications

Even though ytterbium-doped laser get media generally exhibit a small quantum defect, ytterbium-doped tungstates permit for specifically modest values. One example is, a 1030-nm Yb:YAG laser would Ordinarily be pumped all-around website 940 nm, Whilst Yb:KGW or Yb:KYW may very well be most proficiently pumped close to 981 nm.
