Semiconductor-laser apparatus has primary reflective portion and partial reflective portion at one end face, secondary reflective portion at another end face, and laser resonator arranged in optical path formed between end faces

摘要

The apparatus (1) includes primary reflective portion (31) and partial reflective portion (33) provided on one end face (11), and secondary reflective portion (32) provided on another end face (12). A laser resonator is provided in the middle of resonance optical path formed between the primary reflective portion (31) and the partial reflective portion (33), and the secondary reflective portion (32).
