[edit] Paragraph removed from article

I removed this:

At first, ruby lasers used natural rubies, making the commercial and scientific use of lasers a very expense venture. However, the application of lasers become more viable with the invention of the synthetic ruby by John M. Burdick in 1949 (U.S. Patent 2488507), working for Linde Air Products, which was at that time a division of Union Carbide.

since it pre-dates the actual invention of the laser. --Bob Mellish 21:29, 22 May 2007 (UTC)
