Femtosecond laser depending on Yb:KYW crystals with suppression of spectral narrowing within a regenerative amplifier by spectral profiling of the pulse

The absorption and emission spectra of Yb:KYW Crystals display powerful peaks at 980 nm and 1030 nm, respectively, making certain economical Strength conversion and higher general performance in laser programs.

Optical structure of the laser with direct pumping Together with the radiation of semiconductor injection lasers. LD is an IPG Photonics laser diode with fiber output in the radiation, WP is really a half-wave plate, CL can be a collimating lens, FL is often a concentrating lens, AE is surely an active component made from an Yb:KYW crystal, DM is a spherical dichroic mirror, M1-M6 are the cavity mirrors, OC will be the output mirror, and SAM is a semiconductor saturable-absorber mirror.

Adhesion Take a look at Compliant with MIL-C-675C military services requirements, an adhesion examination included implementing a tape that satisfies LT-ninety technical specs on to the lens movie layer. The tape was affixed completely then eradicated vertically. This process was carried out 3 times, leading to no blistering or peeling.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are utilized as lasing components to make ultrashort (~ one hundred-200 fs) large electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser techniques.

A higher brightnessQ-switched oscillator and regenerative amplifier dependant on a dual-crystal Yb:KGW laser

For tungstates, the ytterbium doping focus can be very superior devoid of important quenching since the replaced ions have an exceedingly comparable ion radius, as well as inter-ion length is fairly huge.

By substituting yttrium with ytterbium during the crystal lattice of Yb:KYW a result of the very similar sizes of these chemical features approximately 100% of Yb-doping can be obtained.

The thermal conductivity of prevalent double tungstates is from the order to three–4 W/(K m) �?which isn't terrible compared with other laser crystals (Though numerous periods below for YAG), and pretty big as opposed check here Together with the thermal conductivity of standard Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is really a remarkable product that plays a vital part in laser technological innovation. Its Most important purpose is usually to make ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.

Ask RP Photonics for almost any guidance about tungstate lasers, like femtosecond lasers and higher-electric power lasers.
