Abstract :
The dynamic linewidth of a C3 laser is measured as the gap width between the two cavities is varied. With the modulation applied only to one cavity, the chirping is largest for the gap which maximises spurious mode suppression. With the modulation split optimally between the two cavities, the chirp is smallest for this same gap.
