SEMICONDUCTOR LASER OPTICAL SYSTEM |
摘要 |
<p>An optical system featuring a semiconductor laser for oscillating a beam which has, in a far field pattern, two lobes in the direction aligned with a pn junction interface of the semiconductor laser. The optical system is provided with a total reflection mirror for reflecting part of the beam in such a manner that one of the two lobes is separated from the other, and with a polarization beam splitter having a junction for synthesizing rays in such a manner that the lobes which have been separated by the total reflection mirror are superimposed. The apparatus is thus capable of forming a single beam spot at which the two lobes are superimposed.</p> |
