| 英文摘要 | PURPOSE:To operate stably the title device by low optical power and low operating current and to make it possible to set the interval between resonance peak frequencies according to the interval between the frequencies of an incident light by a method wherein the device is constituted of a semiconductor laser beam amplifier and an external reflecting mirror for constituting a compound resonator. CONSTITUTION:A sphere-tipped rod lens 3 is installed on the side of an end face 1b of a semiconductor laser beam amplifier 1 with a non-reflection coat film 2 formed on the end face 1b on one side of two end faces 1a and 1b of a semiconductor laser 1 having a band of 55mum and the image of a luminous pattern on the end face 1b is formed on a semi-transparent mirror 4. By adjusting the position and angle of the mirror 4, light is made to feedback to the amplifier 1 and a compound resonator is formed between the end face 1a of the amplifier 1 and the mirror 4. By setting the distance between the end face 1a and the mirror 4 in 2cm, the interval between resonance peak frequencies comes to 7.5Hz or thereabouts and can be set in a degree identical with that between high-density FDM transmission channels. |
