This paper describes a femtosecond laser regenerative amplifier based upon two Yb:KYW crystals with direct longitudinal pumping by effective linear arrays of semiconductor injection lasers acquiring fiber output. To circumvent spectral narrowing during amplification and the corresponding lengthening of the amplified pulse when it is compressed, a mix of two Yb:KYW crystals have been employed, Using the spectral maxima of the amplification shifted relative to one another and with spectral profiling of the amplified radiation.
Right before the development of Nd:YAG, Nd3+:CaWO4 was an important scarce-earth-doped laser obtain medium. It was actually Employed in the very first repeatedly functioning crystal laser.
FIG. 1. Optical structure of a laser with immediate pumping Along with the radiation of semiconductor injection lasers. LD is undoubtedly an IPG Photonics laser diode with fiber output
Tungstates have a tendency to acquire significant Raman coefficients (�?Raman scattering). Thus, they might generate considerable Raman achieve at reasonable optical intensities. It is achievable to use the laser crystal itself as being a Raman converter.
