説明

<jats:p>Beam coupling gain and response time together with reflectivity and response time of an external ring phase-conjugate mirror are studied as a function of temperature for a crystal of strontium-barium niobate. The photorefractive sensitivity is increased by a factor of 5 when the crystal is heated to 65 °C. Self-pumped reflectivities up to 19% are observed at room temperature. The reflectivity is smaller at elevated temperature.</jats:p>
