Title:
SEMICONDUCTOR LASER DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075595
Kind Code:
A1
Abstract:
This semiconductor laser device (1) comprises: a housing (2) that has a flat bottom surface (6a); semiconductor laser elements (10–15) that are arranged in the housing (2); fast axis collimator lenses (30–35) that respectively collimate laser beams that are respectively emitted from the semiconductor laser elements (10–15) in a fast axis direction; prisms (40–45) that respectively deflect the laser beams in the fast axis direction; and slow axis collimator lenses (60–65) that respectively collimate the laser beams in a slow axis direction. The prisms (40–45) are arranged between the fast axis collimator lenses (30–35) and the slow axis collimator lenses (60–65), and the laser beams that are respectively emitted from the slow axis collimator lenses (60–65) have different optical axis positions in the fast axis direction from one another.
