  • 589 nm laser
    Patent number: 6654395
    Abstract: The invention provides an improved glass host for a Pr3+-doped glass 589 nm laser. For this purpose, a fluoroaluminate glass, of certain composition ranges, has been determined per the invention. Results indicate good lasing intensity at 589 nm in such fluoroaluminate glass host, particularly at elevated temperatures. The glass can be in the form of fiber, glass rod, or wave-guide.
