Optically pumped ultrashort cavity In_1−xGaxAsyP_1−y lasers: picosecond operation between 083 and 159 μm

Abstract

Ultrashort-cavity, thin-film lasers from In_1−xGa_xAs_yP_1−y of five different compositions, including InP and In_0.53Ga_0.47As, have been made to lase between 0.83 and 1.59 μm. The multitude of lasing wavelengths observed had line-to-line separations of less than 10 nm. The lasers were pumped with 1-psec pulses from a mode-locked dye laser. An output pulse of 6-psec duration was measured at a wavelength of 1.16 μm.
