英文摘要	PURPOSE:To facilitate the adjustment of optical axis by srranging such that the flattened surface of a heat sink block for jointing a semiconductor laser is inclined with respect to a reference line which rules the horizontal surface of a block fixing plate in accordance with the inclination of the laser with respect to the surface of substrate for the active layer. CONSTITUTION:A parallelopiped heat sink block 9 is brazed to a parallelopiped fixing plate 8. The brazing is made such that the reference line BB' of the stem coincides with the axis of the fixing plate 8 while the laser junction surface (a) is inclined at a predetermined angle to the reference line BB'. This angle is equalized to the angle formed between the active layer 3 of the semiconductor laser and the horizontal surface of the substrate. In consequence, the deviation direction gamma of the outcoming light is made parallel to the reference line BB' of the stem, so that it is possible to obtain a stable fundamental lateral mode oscillation by a simple adjustment.
