Paper Abstract

We present a high-temperature-resistant distributed Bragg reflector fiber laser photowritten in Er/Yb codoped fiber that is capable of long-term operating at 500°C. Highly saturated Bragg gratings are directly inscribed into the active fiber by use of the two-photon absorption at 193 nm. After annealing at elevated temperature, the stabilized gratings are strong enough for laser oscillation. The laser operates in robust single mode with output power more than 1 dBm and signal-tonoise ratio better than 70 dB over the entire temperature range from room temperature to 500°C.
