Abstract

We present a high-temperature-resistant distributed Bragg reflector fiber laser photowritten in Er/Yb codoped phosphosilicate fiber that is capable of long-term operation at 500 °C. Highly saturated Bragg gratings are directly inscribed into the Er/Yb fiber without hydrogen loading by using 193 nm excimer laser. After subjected to a significant decay at elevated temperature, the stabilized gratings are strong enough for laser oscillation. The laser operates in robust single longitude mode with output power more than 1 dBm and signal-to-noise ratio better than 70 dB over the entire temperature range from room temperature to 500 °C.
