Abstract

PURPOSE: To reset a bistable laser with light with a moderate precision of wavelength by inputting incident light having a wavelength to be amplified in a gain region of a bistable laser from a light source for resetting to the bistable laser and causing consumption of a carrier in the gain region.
CONSTITUTION: A bistable laser device provided with a bistable laser 1 and a resetting light source 2 is constituted. If the inputted light from the resetting light source 2 is coaxial with the laser light of the bistable laser 1, the wavelength of the inputted light is selected from a region where the absorption of saturable absorption region of light having a longer wavelength than a laser oscillation wavelength is not so strong. A carrier in a gain region of bistable laser 1 amplifies also the light other than those having a laser oscillation wavelength. When such light having a wavelength in an amplifiable wavelength region is inputted from outside, the inputted light is amplified in the gain region, and the carrier is consumed corresponding to an amt. used for the amplification, and laser oscillation is stopped due to decrease of the gain in the laser oscillation wavelength. Thus, bistable laser is reset easily by an optical signal.
