Abstract: PROBLEM TO BE SOLVED: To prevent degradation in recording performance while preventing increase in the size and cost of a light source, in an optical recording system that uses, as a recording light source, an MOPA (Master Oscillator Power Amplifier) that comprises a mode lock laser part including an external resonator, and a semiconductor light modulator used for amplifying and modifying a laser beam emitted from the mode lock laser part.SOLUTION: As an isolator part disposed between the mode lock laser part and the semiconductor amplifier, one composed of a combination of a polarization beam splitter and a 1/4 wavelength plate is provided. This makes it possible to at least remove an SOA self-incident component that is the most influential in an optical recording system, and to prevent degradation in recording performance. Additionally, the comparison with a conventionally used Faraday isolator makes it possible to reduce the size and cost of the isolator part.

Abstract: PROBLEM TO BE SOLVED: To suppress parasitic oscillation by polarization in a laser resonator by a relatively simple configuration. SOLUTION: Laser light source equipment includes an excitation light source 1, and resonator mirrors 2, 3 for composing a resonator 20. The resonator 20 has a laser medium 5 excited by light from the excitation light source 1, thus outputting light obtained by the oscillation of the resonator 20.
