hi, which is the best site that can provide technical information about lasers?

To get a good start, try www.howstuffworks.com.\nLook in the back of a textbook to see where the editors got their information.\nFind out which companies develop/research chemical lasers then look at their websites.

Wikipedia is probably the single best place to go on the internet for general information about just about any topic. It's extremely helpful in answering questions on here.

Laser is used to carry info through optical fibers.\n\nIn fiber optics, transmitters primarily consist of a laser and a modulator. The laser generates the light and the modulator changes the intensity of the laser light in order to couple the data to be transmitted. In effect, the modulator either blocks or passes the laser light depending upon the data signals being fed to it.\n\nThe lasers used in fiber optic communications are similar in many ways to those used at supermarkets and lecture halls. Both types are made in a similar fashion, using semiconductor materials much like the silicon used to make most electronic IC components. However, the one big difference between them is that communications lasers do not generate visible light, but rather infrared light.

Below are some links with some cool diagrams.  I'm not sure if it's specifically what you wanted though.  The second link has some really cool information about spectral transitions in a LASER.

There is a fair selection between these websites\nGood luck\n\nhttp://www.library.fau.edu/depts/ref/rsguide/mechanical/content.htm\nhttp://www.intute.ac.uk/sciences/cgi-bin/browse.pl?id=170

I know one website it is  howstuffworks.com  where you can get almost all information related science, engineering, & technology too. There are thausands of sites related to science while searching through Google you can get some more also.
