Abstract

Frequency shifted feedback (FSF) lasers are lasers which contain an acousto-optic modulator (AOM) as a frequency shifter inside its cavity ^1)-2). We are investigating the oscillation mechanism by using a diode-pumped Nd:YVO₄ as a gain medium. Remarkable information was obtained on the oscillation characteristics, especially on the unique oscillation spectrum³⁾. In this paper, it was made clear for the first time that the oscillation bandwidth is defined as the product of lineshape broadening and total mode number of resonant modes. This was determined by using the proposed model based on multiple-beam interference with phase shift according to round-trip in the cavity.
