Abstract
The semiconductor laser modulehas a first substrate, a second substrateprovided on the first substrate, a semiconductor laser deviceoperable to emit a laser beam L having an optical axis along the Z-direction, a collimator lensconfigured to collimate components of the laser beam L along a direction of a fast axis (Y-direction), and a lens fixture blockhaving a lens attachment surfaceA and a block fixation surfaceB that are perpendicular to the X-direction. An endA of the collimator lensalong the X-direction is fixed to the lens attachment surfaceA of the lens fixture blockwith a lens fixation resin. The block fixation surfaceB of the lens fixture blockis fixed to a side surfaceA of the second substratealong the X-direction with a block fixation resin
