OSI Laser Diode has introduced a product family of high power monolithic stack pulsed laser diodes for a wide variety of military, defence, industrial, automotive, and machine vision applications.
Single and stacked pulsed laser diodes are available up to 375W and fibre-coupled devices are available up to 188W. Custom packaging is also available, upon customer request. The new devices feature stable output from -40°C to +85°C for operation in extreme environments. The rise time is one nanosecond, the laser beam spread is 9 x 25 degrees, and the duty cycle (DC) is 0.1 per cent. The monolithic stack pulsed laser diodes operate at a typical peak wavelength of 905nm (minimum at 895nm and maximum at 915nm) with a spectral width of 8nm. The new family of devices is specified with drive conditions at 100ns, 30 Amps, 1 kHz at 25°C. Peak power at 25°C ranges from 60, 120, 180, 240, and 300W, depending on the specific device required.
