    摘要: A semiconductor laser array device has a relatively wide light-emitting area with many semiconductor lasers and a shielding layer selectively disposed with respect to peripheral regions of the light-emitting area such that the rate of heat emission from the center part can be increased relative to that from the peripheral regions. Temperature distribution on the light-emitting area can thus be made uniform and laser light can be emitted from the entire laser emitting area under a phase-synchronized condition.
