[edit] Superluminescent lasers
"some lasers do not use an optical cavity, but instead rely on very high optical gain to produce significant amplified spontaneous emission (ASE) without requiring feedback of the light back into the gain medium. Such lasers are said to be superluminescent"
Isn't this called superradiant lasing? When the gain is so high, such as in N2 lasers, there is no need for an FP resonator...?--Deglr6328 03:35, 26 December 2005 (UTC)
- Not exactly sure. I've seen them called superluminescent, superradiant, or superfluorescent lasers, with no clear distinction between them. And of course some people don't call them lasers at all. I'm following here: [1], which suggests "superluminescent" is most accurate, though I'll hunt for a primary source. --Bob Mellish 15:09, 26 December 2005 (UTC)
