The Yb:KYW crystal’s proficiency in gentle absorption at all over 981 nm helps make the crystal well matched for diode pumping. It truly is further more Increased by its amazing efficiency in this process, coupled with its minimal quantum defect.
The absorption and emission spectra of Yb:KYW Crystals Screen sturdy peaks at 980 nm and 1030 nm, respectively, making sure economical Vitality conversion and significant efficiency in laser systems.
Optical structure of the laser with direct pumping Using the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output from the radiation, WP can be a fifty percent-wave plate, CL can be a collimating lens, FL is really a concentrating lens, AE can be an Energetic aspect constructed from an Yb:KYW crystal, DM can be a spherical dichroic mirror, M1-M6 are definitely the cavity mirrors, OC is the output mirror, and SAM can here be a semiconductor saturable-absorber mirror.
The monoclinic crystal constructions results in a purely natural birefringence, assisting to prevent thermally induced polarization rotation and depolarization decline.
Raman, luminescence and transmission spectra expose optical options owing towards the presence of thulium ions, and thus the resources may very well be additional researched from the scope of laser and luminescence programs.
A higher brightnessQ-switched oscillator and regenerative amplifier according to a dual-crystal Yb:KGW laser
For tungstates, the ytterbium doping concentration can be extremely higher with out important quenching as the changed ions have a very equivalent ion radius, along with the inter-ion distance is comparatively huge.
High-energy repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes
The thermal conductivity of popular double tungstates is on the order to 3–four W/(K m) �?which isn't undesirable compared with other laser crystals (Whilst numerous occasions lower than for YAG), and rather big in comparison Along with the thermal conductivity of common Eyeglasses.
