Abstract

A laser cavity closed via the first-order diffracted light of an acousto-optic modulator is referred as a frequency-shifted feedback laser (FSFL).¹ The laser exhibit outstanding features in its oscillation spectrum.² We previously demonstrated the first oscillation of all-solid-state FSFL,³ and it was made clear that internal structure of the spectrum consists of a continuously-chirped comb of frequency components. Furthermore, oscillation dynamics have been under our investigation both experimentally and theoretically for a better understanding of FSFL. Here we discussed its oscillation bandwidth as a function of the output coupler reflectance.
