These tutorial pages have been written for those who have little or no knowledge of lasers. There are five sections in total and it is suggested that they are read in the sequence 1 to 5. Text items in green are links to further information on the item concerned. These should be ignored by anyone whose primary aim is to find out quickly and in general terms how lasers work. However, some acquaintance with the wave theory and the photon theory of light would be helpful. For other information on basic optics and the properties of light see the Light Measurement Handbook. Lasers come in wide variety of forms, the processes that go on inside them differing greatly from one type of laser to another. For this reason, it is easy to become distracted by detail that might apply to one type of laser only. In this tutorial, an attempt has been made to concentrate on those features that lasers have in common. |
