11. Aluminium gallium arsenide ( AlGaAs ) is used in high-power infrared laser diodes . 12. LEDs, laser diodes etc . ) are descendants of Ohl's work. 13. Laser diodes are created by laying down remarkably thin layers of semiconducting materials.14. The reliability of a laser diode can make or break a product line. 15. The LTI Criterion 400 uses an infrared semi-conductor laser diode for slope distance measurement. 16. Infrared light at 900 nm from 8 arrays of laser diodes pumps the laser. 17. Nowadays synthetic diamond is used as submounts for high-power integrated circuits and laser diodes . 18. Laser diodes are also frequently used to optically pump other lasers with high efficiency.19. Laser diodes are also used for better resolution and precision.20. The convection experiment uses a laser diode to illuminate particles suspended in silicone oil.
