LASERS

Laser F/X's Laser Science Projects page http://www.LaserFX.com/Science.html provides some information and resources for science projects. Resources provided include a bibliography, a glossary of terminology used in laser displays, a listing of other applications of lasers, basic laser safety, and a listing of other WWW laser resources. In addition, there is a page with suggestions for high school science projects involving lasers as well as some pages with images and drawings you may use in your projects provided you follow the rules on the page.

Lawrence Livermore National Laboratory's All About Lasers http://lasers.llnl.gov/lasers/about.html has general laser information, a newsgroup for people with interests in lasers and their applications, information on how a laser works, a brief introduction to lasers at the high school or undergraduate college level, history of the laser and types of lasers, a Laser Education section which contains education and public outreach oriented web sites, and a Lasers at LLNL link to information about the Nova Laser Facility.

Laser Tutorial http://members.aol.com/WSRnet/tut/ut1.htm is a web science resource presented by Lasers-Optics-USA. It consists of tutorial pages written for those who have little or no knowledge of lasers. There are five sections in total and it is suggested that the sections are read in the sequence 1 to 5. Lasers come in a wide variety of forms, the detailed processes that go on inside them differing greatly from one type of laser to another. In this tutorial, an attempt has been made to concentrate on those features that lasers have in common.

The Laser Adventure http://www.phys.ksu.edu/perg/vqm/laserweb/index.htm is a course on lasers and their applications which was developed for Grades 11-12, and college level. It explains the basic physical principles of laser operation, and describes many types of lasers, and many applications of lasers.

LaserNet http://www.rli.com/index.html has laser and laser safety links.

Purple Crow Lidar (PCL) http://pcl.physics.uwo.ca/ is a laser radar which operates from a University of Western Ontario research facility near London, Canada. The powerful laser is used to take measurements which allow air density, pressure, and temperature to be determined and will be used to address the question of global warming in addition to contributing to our ability to predict weather.

Laser Scissors and Tweezers http://www.sciam.com/1998/0498issue/0498berns.html is a feature article from the April 1998 Scientific American Online edition. Lasers offer new ways to investigate and manipulate cells. This article discusses how researchers are using lasers to grasp single cells and tinier components in vises of light while delicately altering the held structures.
