Product Overview
The QL65I7SA/B/C-H series is a 30mW red laser diode supplied in a compact 5.6mm metal-can package with an integrated monitor photodiode.
The series is designated as a 650nm red laser, with a typical lasing wavelength of 658nm at the datasheet test conditions. It supports continuous-wave operation and features single-transverse-mode output with TE polarization.
Three internal circuit configurations are available: QL65I7SA-H, QL65I7SB-H and QL65I7SC-H. Select the configuration that matches your driver circuit.

Operating Requirements
This product is a laser diode component, not a complete powered laser module. The datasheet specifies operation with automatic power control (APC) and a heatsink. Match the driver to the selected internal circuit type.
The typical 2.4V operating voltage is the diode's forward voltage at the stated test conditions, not a direct power-supply connection specification.
Package Includes
- 1 × Red laser diode in the selected part number and circuit type
Driver, heatsink, collimating optics and power supply are not included.
