Passive mode locking of a Tm:Sc2O3 laser at around 2 μm and 2.1 μm is reported. The shortest pulse duration of 218 fs is achieved with an average power of 210 mW at 2107 nm.
We report the use of a near-resonant GaInNAs SESAM in a Cr4+:forsterite laser to generate transform-limited 150fs pulses around 1300nm at a repetition-rate of 0.65GHz with average powers up to 270mW.
Here we report on the growth of a novel Tm,Ho:KYW laser crystal, together with its spectroscopic properties and lasing characteristics obtained using cw Ti: sapphire laser pumping at room temperature.
