IPC: H01S5/40
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce a deviation from a designed value of repetition frequency of optical pulse by measuring an RF spectrum by an RF spectrum analyser for evaluation of beat frequency, and conforming the beat frequency with a desired pulse repetition frequency of laser. SOLUTION: A constant d.c. current or a pulse current with a duty of 10% or more is allowed to flow in the gain part of one laser in a bar 2 by using an electric probe 7 for a laser oscillation. A laser light obtained from the end surface of laser in this state is coupled with an optical coupler 10, so as to convert an optical signal into an electric signal. Then the electric signal is amplified by a high-frequency amplifier 11, and its RF spectrum is measured by an RF spectrum analyser and the beat frequency is evaluated thereafter. The evaluated beat frequency is coincident with a desired pulse repetition frequency. Thus, a deviation from a designed value of repetition frequency of optical pulse can be reduced.
