Abstract

PURPOSE:To provide a semiconductor laser device on which a less influence is exerted by a laser light, by a method wherein a side facing a penetration window is formed obliquely at a part of a package whereto a laser chip is bonded. CONSTITUTION:The difference of the new invention from a conventional type is the shape of a block 4, and the upper surface of the block 4 is cut off obliquely to form a slope 10. This causes a penetration window 7 to reflect a part of light radiated from a semiconductor laser chip 5. Even if it enters the block 4, the reflection light does not advance toward the window 7, but advances toward corners of a package 1, and does not come out of the package 1. This reduces an influence of the reflection light and permits to obtain a radiation property having an improved symmety.
