Efficient self-pumped phase conjugation with a loop geometry in a Rhodamine-6G solid dye laser amplifier

Opt Express. 2003 Jan 27;11(2):176-80. doi: 10.1364/oe.11.000176.

Abstract

We present what to our knowledge is the first demonstration of self-pumped phase conjugation in a laser-pumped solid-state Rhodamine-6G dye saturable amplifier. Phase-conjugate energy reflectivity of as much as 2100% at 557 nm has been obtained.
