Sapphire Fiber Sensors Withstand Extreme Temperatures
Dr. Julian Fells and his team at the University of Oxford, Department of Engineering Science have developed sapphire fiber sensors that can withstand extreme temperatures. These sensors have the potential to increase efficiency and reduce emissions in aerospace and power generation. Light Conversion is very proud to have supplied the PHAROS femtosecond laser for this research. This industrialized femtosecond laser was used to inscribe novel structures into optical fibers to sense parameters such as temperature, pressure, and strain.

PHAROS is a series of femtosecond lasers combining millijoule pulse energy and high average power. PHAROS features a mechanical and optical design optimized for both scientific and industrial applications. A compact, thermally-stabilized, and sealed design enables PHAROS integration into various optical setups and machining workstations. Diode-pumped Yb medium significantly reduces maintenance costs and provides a long laser lifetime, while the robust optomechanical design enables stable operation in varying environments.
Features of PHAROS:
- 100 fs – 20 ps tunable pulse duration
- 3 mJ maximum pulse energy
- 20 W maximum output power
- Single-shot – 1 MHz repetition rate
- Pulse picker for pulse-on-demand mode
- Automated harmonic generators (up to 5th harmonic)
- CEP stabilization option
- Repetition rate locking to an external source
