Self-injection locked laser via a hollow-core fiber Fabry–Perot resonator
Original language description
In a hollow-core fiber (HCF), light propagates through an air/vacuum core rather than a solid material, resulting in a low thermo-optic coefficient and ability to handle high powers. Here, we demonstrate a laser locked to a hollow-core fiber reference, which thanks to the low HCF thermal sensitivity, shows long-term stability an order of magnitude better than compact commercially available low-noise lasers. The laser frequency variation within +-600 kHz was measured over 50 h. The stability of our proof-of-concept laser is ensured via a strong self-injection ratio of -15 dB, enabled by the high-power handling and low loss of the hollow-core fiber’s resonator. Moreover, our results show appealing performance parameters, including a fractional frequency stability of 4 x 10^-13 at 1 s averaging time and a Lorentzian component of the linewidth of 0.2 Hz.
