Abstract :
Picosecond pulse generation by active mode locking has been achieved simultaneously at two wavelengths using a multichannel grating cavity Laser. For a spectral channel separation of 2.2 nm, pulses of duration of 60 ps and with a spectral width of 11 GHz have been obtained. The pulse widths are limited by the spectral dispersion of the grating used.<>
