31. Laser diodes with the right color and enough power are both expensive and in short supply.32. Laser diodes are also used for better resolution and precision, improving performance on opaque specular surfaces.33. Electric current is typically used to pump laser diodes and semiconductor crystal lasers ( for example germanium) 34. Clemson's machine uses a laser diode that shines infrared light through a breast at 16 different points. 35. Laser diodes built with the same technology drive the flow of information in the Internet's fiber-optical cables.36. One obvious idea I had was to use laser diode and a detector like an optical mouse. 37. Compared with direct modulation of the laser diode , a higher bandwidth and reduced chirp can be obtained. 38. Low to medium power laser diodes are used in laser pointers, laser printers and CD / DVD players. 39. Laser diodes find wide use in telecommunication as easily modulated and easily coupled light sources for Blu-ray technology.40. :I'm guessing that there is some kind of alignment problem with the laser diode in your CD player.
