Abstract
Two types of novel two-photon sensitized recording media were developed; the fluorescent dye generation type media and fluorescent quench type media, and two-photon recording inside both the media using femtosecond laser was demonstrated. The signal modulation vs. recording power relationship showed quadratic dependency in both the media. The obtained fluorescent signal intensity from the quench type media is several times higher than that from the fluorescent dye generation type media.
