785nm, 100mW laser diode in a TO-CAN 5.6mm package with monitoring PD sealed with glass cap.Drawn from the datasheet (https://www.lasercomponents.com/fileadmin/user_upload/home/Datasheets/qd-laser/qlf073a_qlf073d.pdf) with the help of the excellent ImageJ (https://imagej.nih.gov/ij/).The elliptical aperture through the glass window represents the laser beam (not to scale). The red surface behind the window is the laser emitting surface.
