We present a twin-crystal Yb:KGW laserthat iscapable to function as being a Q-switched oscillator with output power nearly 24 W and pulse size of twenty ns,or for a regenerative amplifier with output electricity up to 21 W and pulse length underneath 200 fs immediately after compression of chirped pulses. The two lasers have excellent beam top quality with beam parameter M2
Coloration-coded reflectivity of the Bragg mirror as being a perform of wavelength and angle from the 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 obtaining fiber output. To stop spectral narrowing all through amplification and also the corresponding lengthening on the amplified pulse when it is compressed, a combination of two Yb:KYW crystals were applied, Along with the spectral maxima of the amplification shifted relative to each other and with spectral profiling on the amplified radiation.
Right before the event of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It had been in fact used in the 1st continuously working crystal laser.

Tungstates are likely to have higher Raman coefficients (�?Raman scattering). As a result, they will crank out sizeable Raman attain at average optical intensities. It can be done to use the laser crystal itself as a Raman converter.

... Not merely the placement of crystal within the cavity but additionally the amplification axis of crystal impacts the laser operation tremendously, because the absorption and emission cross sections of the crystal are pretty distinct based on the orientation with the crystal.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) when compared to its counterpart Yb:KGW, is often a amazing content that plays an important job in laser technological know-how. Its KYW Crystal Most important functionality will be to create ultrashort pulses of sunshine, spanning only a few hundred femtoseconds.
