This paper describes a femtosecond laser regenerative amplifier according to two Yb:KYW crystals with direct longitudinal pumping by powerful linear arrays of semiconductor injection lasers acquiring fiber output. To avoid spectral narrowing during amplification as well as the corresponding lengthening of the amplified pulse when it can be compressed, a combination of two Yb:KYW crystals ended up employed, with the spectral maxima in the amplification shifted relative to each other and with spectral profiling with the amplified radiation.
Prior to the development of Nd:YAG, Nd3+:CaWO4 was a very important rare-earth-doped laser gain medium. It absolutely was in truth Utilized in the primary continually working crystal laser.
PDF Yb:KGW and Yb:KYW crystals have broad emission bandwidths and are applied as lasing supplies to make ultrashort (~ 100-200 fs) superior electrical power pulses. Immediate pump of Yb:KGW/KYW crystals with laser diodes operating at 981 nm supports compact laser techniques.
Tungstates are inclined to obtain large Raman coefficients (�?Raman scattering). Thus, they are able to produce major Raman obtain at average optical intensities. It can be done to utilize the laser crystal itself as being a Raman converter.

On the other hand, when Nd3+:YAG turned commercially accessible, the interest in CaWO4 dropped sharply. In afterwards several years, selected other tungstate crystals began to bring in many focus.
The thermal conductivity of widespread double tungstates is of the purchase to 3–4 W/(K m) �?which isn't undesirable compared with other laser crystals (Even though get more info numerous times fewer than for YAG), and relatively big as opposed Using the thermal conductivity of common glasses.

Simultaneously, a shorter laser wavelength is often received; it is achievable to function that has a quantum defect very well under 1%. As being a consequence, the warmth technology might be so modest that this partly compensates the lessen thermal conductivity.
