The Yb-doped potassium yttrium tungstate (Yb:KYW) crystal, as compared to its counterpart Yb:KGW, is actually a remarkable substance that plays an essential purpose in laser technologies. Its Most important perform is usually to crank out ultrashort pulses of sunshine, spanning just a couple hundred femtoseconds.
Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing inside of a regenerative amplifier by spectral profiling of the heartbeat
Color-coded reflectivity of the Bragg mirror as being a functionality of wavelength and angle in the incident beam.
This paper describes a femtosecond laser regenerative amplifier depending on two Yb:KYW crystals with immediate longitudinal pumping by effective linear arrays of semiconductor injection lasers having fiber output. To forestall spectral narrowing through amplification along with the corresponding lengthening from the amplified pulse when it is actually compressed, a combination of two Yb:KYW crystals have been made use of, With all the spectral maxima with the amplification shifted relative to one another and with spectral profiling from the amplified radiation.
Soon after air drying and subsequent cleansing which has a cotton fabric soaked in alcohol, the film surface showed no indications of peeling or scratches.
PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are used as lasing elements to produce ultrashort (~ 100-two hundred fs) high electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes working at 981 nm supports compact laser units.
A large brightnessQ-switched oscillator and regenerative amplifier according to a twin-crystal Yb:KGW laser

Higher-electricity repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical apps
The thermal conductivity of common double tungstates is on the get to 3–4 W/(K m) �?which isn't lousy in contrast with other laser crystals (While various instances a lot less than for YAG), and fairly huge when compared While using the thermal conductivity of typical glasses.
