The output frequencies of diode lasers spectrally narrowed by optical feedback have been stabilized to hyperfine components of the rotation-vibration transition R (92) 0–15 at λ = 793.23 nm. Laser linewidths of less than 100 kHz and frequency stabilities or 4×10 −11 for τ = 1 s (square root of the Allan variance) were measured by beat experiments of two independent lasers. The influence of the iodine pressure on the linewidth and on the positions of the hyperfine components has been investigated. The total hyperfine pattern has been fitted with an effective hyperfine Hamiltonian to a standard deviation of 23 kHz.
