Generation of a wide-range and stable THz waves from a photoconductive antenna excited by a multimode semiconductor chaotic oscillation laser with an optical delayed feedback using an external mirror is investigated. A high bias voltage is also used to generate wide range THz wave. The THz wave near to 1 THz is obtained using this system.
Generation of a wide-range THz wave from a photoconductive antenna excited by a multimode semiconductor chaotic oscillation laser with an optical delayed feedback using an external mirror is investigated. An optical fiber is also used for easy alignment. The properties of the generated THz wave are compared with those of generated THz wave by using a CW steady state laser.
