| 英文摘要 | PURPOSE:To equalize the shape of the wave surface of laser beams regardless of a temperature change by selecting the linear expansion coefficients of a supporter, etc. and the refractive index of a collimator lens when a semiconductor laser is mounted at one end of a cavity section in the supporter and the lens at the other end and laser luminous flux projected is changed into parallel luminous flux by using the lens. CONSTITUTION:A heat sink 16, on the inside thereof is photodiode 18 for monitoring is fitted, is fixed at one end of a cavity section constituted by screwed two supporters 20 and 22, a semiconductor laser 10 is fastened near an end section on the inside of the heat sink through a sub-mount 14, and these apparatus are sealed with a cap 30 with a projecting window 28. A collimator lens 12 settled by lens cells 24 and lens hold-downs 26 is mounted at the other end of the cavity section, and laser beams are projected as parallel luminous flux PL. In the constitution, the linear expansion coefficients of constitutional members, such as the supporters, etc. and the change of the refractive index of the lens due to the variation of laser oscillating wavelengths are offset, thus bringing the wave surface of laser luminous flux to a plane at all times. |
