This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by powerful linear arrays of semiconductor injection lasers acquiring fiber output. To stop spectral narrowing all through amplification and also the corresponding lengthening from the amplified pulse when it's compressed, a mix of two Yb:KYW crystals ended up employed, While using the spectral maxima from the amplification shifted relative to one another and with spectral profiling on the amplified radiation.

Immediately after air drying and subsequent cleansing having a cotton fabric soaked in alcohol, the movie surface confirmed no signs of peeling or scratches.

PDF Yb:KGW and Yb:KYW crystals have wide emission bandwidths and therefore are used as lasing products to generate ultrashort (~ a hundred-200 fs) large electricity pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser units.

five mm in addition to the center of the beam caustic. So as to check the manner matching simulation, we executed the experiment with Ng-Lower crystal oscillator, which was made previously As well as in a exact same affliction with simulation [11]. As revealed in Figure three(b) with red dots and line, the CW output electricity is highly dependent on the placement of laser crystal plus the experimental end result coincides well with simulation outcome. As a Be aware, multimode operation happened in experiment in the event the measurement on the pump beam is bigger than TEM00 cavity mode and it triggers higher CW output energy while in the displacement region below 3.5 mm.

Substantial-electrical power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical purposes

Even though ytterbium-doped laser gain media usually exhibit a little quantum defect, ytterbium-doped tungstates allow for notably modest values. One example is, a 1030-nm Yb:YAG laser would Typically be pumped all around 940 nm, whereas Yb:KGW or Yb:KYW may be most effectively pumped all around 981 nm.

Li2WO4-WO3 flux was successfully utilized reducing the growth temperature under 900 oC. Based on one crystal x-ray measurements, the crystal corresponds on the P2/n Place team.
