This paper describes a femtosecond laser regenerative amplifier based on two Yb:KYW crystals with immediate longitudinal pumping by effective linear arrays of semiconductor injection lasers getting fiber output. To circumvent spectral narrowing in the course of amplification and also the corresponding lengthening of your amplified pulse when it truly is compressed, a combination of two Yb:KYW crystals ended up utilized, While using the spectral maxima in the amplification shifted relative to one another and with spectral profiling from the amplified radiation.

Just after air drying and subsequent cleaning that has a cotton cloth soaked in Liquor, the movie surface area confirmed no indications of peeling or scratches.

PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and so are utilised as lasing resources to make ultrashort (~ one hundred-200 fs) large electrical power pulses. Direct pump of Yb:KGW/KYW crystals with laser diodes functioning at 981 nm supports compact laser programs.

Tungstates tend to possess substantial Raman coefficients (�?Raman scattering). Consequently, they're able to create major Raman obtain at moderate optical intensities. It is achievable to use the laser crystal alone as a Raman converter.

High-electric power repetitively pulsed ytterbium lasers with supershort pulse width and immediate diode pumping for technological and biomedical applications

The thermal conductivity of widespread double tungstates is with the get to 3–four W/(K m) �?which isn't undesirable as opposed with other laser crystals (Whilst quite a few instances less than for YAG), and rather massive compared While using the thermal conductivity of standard Eyeglasses.

Yb:KYW crystal (Yb-doped potassium yttrium tungstate) more info compared to its counterpart Yb:KGW, is a exceptional material that performs a crucial job in laser technologies. Its Key operate should be to produce ultrashort pulses of sunshine, spanning just a few hundred femtoseconds.

At the same time, a shorter laser wavelength is usually acquired; it is feasible to operate by using a quantum defect very well down below one%. As a consequence, the warmth generation may be so compact that this partly compensates the decreased thermal conductivity.
