Double phase conjugate mirror with x6 gain in photorefractive BaTiO3 at near infrared wavelengths

G.W.Ross, R.W.Eason

Abstract

We describe incoherent beam coupling using the double phase-conjugate mirror arrangement between a laser diode and a Ti:sapphire laser at the near-infrared wavelengths of ~800nm using a nominally undoped sample of BaTiO3. We report phase-conjugate reflectivities of greater than 6 times, which we believe to be the highest reported to date at these wavelengths. We also examine the fidelity of the phase-conjugate beam and the wavelength response of the double-color-pumped oscillator.
