Filed: 2003-04-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor laser device which is capable of outputting a high power, operating at high temperatures, and has a laser emission profile of low ellipticity.  <P>SOLUTION: The semiconductor laser device is equipped with a ridge stripe and a layer where the ridge stripe is embedded. A part of the layer, where the ridge stripe is embedded, close to a laser projection end face is set lower in refractive index than the rest of the layer. It is preferable that the width W of a part of the layer near to the laser projection end face is set at 10 to 50 μm from the laser projection end face, and it is also preferable that a part of an active layer near to the laser projection end face has an end face window structure that never absorbs laser rays. Laser rays emitted from an optical disk semiconductor can be made to have an emission profile of low ellipticity through a simple method as a low threshold current, an excellent characteristic temperature, and a high differential efficiency necessary for a high output and a high-temperature operation are retained. Therefore, an optical disk pickup of a simple structure can be manufactured without reducing it in light utilization efficiency, so that the optical pickup can be reduced in size and weight and made speedy of access.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
