Search for: [Abstract = "The Cr3\+\: LiSAF crystal is widely used as a laser medium of a wide gain spectrum from 700 nm to 920 nm. Our numerical investigations demonstrate a spectro\-temporal evolution in the broadband Cr3\+\: LiSAF laser emission from Fabry\-Perot resonator and particularly, from a low – Q resonator. Furthermore, the resonator transient and the phenomenon of relaxation oscillations in the solidstate Cr3\+\: LiSAF laser have been studied. Interestingly, using a diode\-pump pulse of 100 μs at 670 nm, a stable generation of single nanosecond Cr3\+\: LiSAF laser pulse at 850 nm is obtainable by simple choices of resonator parameters such as photon\-cavity time and pump level. A pulse compression factor of 1 000 is achievable. As a result, a simple technique of short laser pulse generation at a high repetition rate of diode pumping pulses has been proposed."]
