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

Colour-coded reflectivity of a Bragg mirror for a functionality of wavelength and angle of your incident beam.

This paper describes a femtosecond laser regenerative amplifier dependant on two Yb:KYW crystals with immediate longitudinal pumping by strong linear arrays of semiconductor injection lasers owning fiber output. To circumvent spectral narrowing all through amplification plus the corresponding lengthening in the amplified pulse when it's compressed, a mix of two Yb:KYW crystals have been used, While using the spectral maxima on the amplification shifted relative to one another and with spectral profiling on the amplified radiation.

Before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser achieve medium. It absolutely was actually Utilized in the main continuously working crystal laser.

PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and so are applied as lasing resources to create ultrashort (~ check here a hundred-200 fs) higher ability pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser units.

five mm besides the middle on the beam caustic. As a way to Verify the manner matching simulation, we done the experiment with Ng-Slash crystal oscillator, which was designed Beforehand and in a similar condition with simulation [11]. As demonstrated in Figure three(b) with purple dots and line, the CW output electricity is highly dependent on the placement of laser crystal as well as experimental result coincides properly with simulation consequence. To be a note, multimode Procedure transpired in experiment if the dimensions of your pump beam is bigger than TEM00 cavity mode and it leads to greater CW output energy in the displacement region down below three.5 mm.

By substituting yttrium with ytterbium while in the crystal lattice of Yb:KYW due to equivalent sizes of such chemical factors as much as a hundred% of Yb-doping could possibly be achieved.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) in comparison with its counterpart Yb:KGW, is actually a exceptional materials that performs a very important purpose in laser know-how. Its Principal perform is to crank out ultrashort pulses of light, spanning just some hundred femtoseconds.
