Title: Semiconductor laser device
Inventor: NITORI KOICHI
IPC: H01S5/06
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To reduce the return light noise of an optical disk by allowing plural semiconductor laser elements for emitting the laser beams of different wavelengths to have the same mitigation vibration frequency. SOLUTION: The two semiconductor laser elements 2 and 3 are closely arranged at a prescribed interval on a sub mounting substrate 4 and mounted so as to make the emission plane of the laser beams be the same plane. In this case, in order to make the return optical noise lowest, the parameter and shape of respective layers for constituting the semiconductor laser elements 2 and 3 are optimized. When defining the delay time of return light as tp0, a self exciting vibration pulse number as fp0 and the mitigation vibration frequency as fR, the return light noise becomes lowest when a standardized distance tp0fp0 is 0.2-0.4. Normally, since it is fp0≈fR, it becomes lowest when fp0fR is in the range of 0.2-0.4. When the mitigation vibration frequency fR of the semiconductor laser elements is made the same, tp0fR becomes the range of 0.2-0.4 and the return light noise becomes lowest.
