Abstract

In this paper, we present a 80-times phase conjugation for pico-second pulses by four-wave-mixing (FWM) in a diode-pumped Nd:YVO/sub 4/ slab amplifier. The reflectivity is the highest value, to the best of our knowledge, obtained by phase conjugation in pico-second regime.

Summary from only given. We present a phase conjugate reflectivity of 150-times obtained by DFWM from a CW diode-pumped Nd:YVO/sub 4/ slab amplifier. To the best of our knowledge, the reflectivity value is the highest ever obtained previously by four wave mixing in a CW saturable amplifier.

High-phase-conjugate reflectivity (>800%) obtained by degenerate four-wave mixing in a continuous-wave diode-side-pumped Nd:YVO_4 amplifier

High-phase-conjugate reflectivities of >800% have been achieved through degenerate four-wave mixing in a cw diode-side-pumped Nd:YVO(4) amplifier. Reflectivity curves are shown as a function of input pump-beam intensity for three values of small-signal amplifier gain, and comparison is made with a numerical simulation.

Continuous-wave and pulsed phase conjugation in Nd:YVO/sub 4/

A. Brignon, J.-P. Huignard

Summary form only given. We have demonstrated efficient cw DFWM in a Nd:YVO/sub 4/ amplifier. The use of long pulses provides an interesting link between the short pulse and the cw regimes. Transient peak reflectivities have been clearly shown at high intensities. Nd:YVO/sub 4/ combined with a high-power cw diode pumping could perform (as demonstrated in the pulsed regime) compact, efficient and all-solid-state cw phase conjugators for the near-IR.

We demonstrate 2.5 times phase conjugation by four-wave-mixing with the use of pico-second pulses in a rhodamine6G dye polymer amplifier. Phase conjugation pulse shortening by a factor of 2 is also measured.

Phase conjugation by saturable-gain degenerate four-wave mixing in solid state laser media

A. Brignon, Jean‐Pierre Huignard, Henri J. Rajbenbach

We present a method to achieve phase conjugation based on saturable-gain degenerate four- wave mixing in the laser medium itself. Experimental and theoretical investigations show that phase conjugate reflectivities and efficiencies higher than 100% can be achieved with such an interaction. High conjugate-reflectivity at (lambda) equals 1.06 micrometers is demonstrated in conventional flash-pumped Nd:YAG amplifiers and in compact diode-pumped Nd:YVO4 amplifiers.
