Femtosecond laser according to Yb:KYW crystals with suppression of spectral narrowing in a very regenerative amplifier by spectral profiling of the pulse

FIG. four. Autocorrelation perform of the heartbeat 共a兲and spectrum 共b兲of a laser with a rectangular Energetic ingredient for an output energy of seven hundred mW. The width of

This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by highly effective linear arrays of semiconductor injection lasers acquiring fiber output. To forestall spectral narrowing for the duration of amplification as well as the corresponding lengthening from the amplified pulse when it is compressed, a mix of two Yb:KYW crystals had been used, Along with the spectral maxima in the amplification shifted relative to one another and with spectral profiling in the amplified radiation.

Right before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It had been in fact used in the primary continuously operating crystal laser.

Spatial framework of your beam as well as the corresponding intensity profiles I with the output on the laser.

For tungstates, the ytterbium doping concentration can be very superior without having sizeable quenching because the replaced ions have a very equivalent ion radius, as well as inter-ion distance is comparatively massive.

Superior-electrical power repetitively pulsed ytterbium lasers with click here supershort pulse width and immediate diode pumping for technological and biomedical applications
