Abstract
An all-solid-state tunable mid-infrared coherent source based on a quasi-ph ase-matched (QPM) difference frequency generation (DFG) is reported. The QP M-DFG was carried out by mixing a spectrally narrowed Cr3+:LiSrAlF6 laser w ith a diode laser (1020 nm) in a bulk periodically-poled LiNbO3 (PPLN) crys tal with single grating period of 22.2 mu m. Wide tuning range around 4.0 a nd 4.6 mu m was obtained by tuning the laser and altering the PPLN temperat ure between 20 and 40 degrees C. Even wider tuning range is expected by opt imizing the PPLN grating period and expanding the tuning range of the Cr3+: LiSrAlF6 laser.
