Simultaneous multiwavelength generation from a mode-locked all-solid-state Cr:forsterite laser

We demonstrate a multiple-channel, mode-locked, all-solid-state Cr:forsterite laser. By inserting an etalon into the laser cavity, we have generated 12 phase-locked channels with 9-19-ps pulse width near 1230 nm with 280-mW average output power from a single laser oscillator. By tuning the etalon bandwidth we can shorten the pulse width in a specific channel to 1.8 ps.
