Abstract

Summary form only given. Vectorial phase conjugation (VPC) is an effective technique of eliminating phase and polarization aberrations in optical systems. Applications of VPC in visible region include optical image processing and optical computing. We present what we believe the first demonstration of visible vectorial phase conjugator (VPC) in a laser-pumped polymer laser dye Rhodamine 6G in PMMA matrix.

Vector Phase Conjugation in Saturable Media

R.P.M. Green, K. S. Syed, Santiago Camacho-López +1 more

Vectorial phase conjugation (VPC) is an effective way of eliminating both phase and polarisation distortions in optical systems and is of special interest in solid-state amplifiers operating at high average powers in which the amplified radiation can become depolarised. There have been experimental demonstrations of VPC in two-photon resonant media and in media with local response [1,2]. This paper presents experimental results of the phase conjugate reflectivity and fidelity of VPC in saturable media (Cr4+:YAG and inverted Nd3+:YAG).

Vector phase conjugation and its implementation in holographic laser resonators

R.P.M. Green, Santiago Camacho-López, Darren Udaiyan +2 more

Summary form only given. In this paper, vector phase conjugation (VPC) is demonstrated both in a saturable absorber (Cr/sup 4+/:YAG) and a gain material (Nd:YAG) for the first time, to our knowledge. We present resuits that show that four wave mixing (FWM) in both of these materials can compensate for large polarization aberrations.

Phase Conjugation by Degenerate Four-wave Mixing in Inverted Dye Solutions

P.A. Routledge, Terence A. King

Phase conjugation has been observed in an amplifying medium of rhodamine 6G dye molecules in solution, excited either by flashlamps or by a laser. It is found that the mechanism involved in phase conjugation is degenerate four-wave mixing through gain saturation, and reasonable agreement obtained with the theory of saturable amplifiers. A phase-conjugate signal was observed over the tuning range of the dye system (580–605 nm) and a reflectivity up to a maximum of 25% was obtained.

Hideki Watanabe, Takashige Omatsu, Mitsuhiro Tateda

Summary form only. Tunable phase conjugation in the visible region has received much attention in several application fields such optical image processing, spectroscopy and medical optics in recent years. In this paper, we present an efficient injection-seeded Rhodamine 6G solid-dye laser cavity, which exhibits phase conjugate energy-extraction of >13,000% in the broad-band from 558 nm to 564 nm.
