Doppler-free frequency modulation spectroscopy of atomic erbium in a hollow cathode discharge cell

, 2011
The erbium atomic system is a promising candidate for an atomic Bose-Einstein condensate of atoms with a non-vanishing orbital angular momentum ($L \neq 0$) of the electronic ground state.

High-bandwidth transfer of phase stability through a fiber frequency comb

, 2015
We demonstrate phase locking of a 729 nm diode laser to a 1542 nm master laser via an erbium-doped-fiber frequency comb, using a transfer-oscillator feedforward scheme which suppresses the effect of comb noise in an unprecedented 1.8 MHz bandwidth.

Optical bistability in diode-laser amplifiers and injection-locked laser diodes

Optics Letters, 1993
Static and dynamic properties of dispersive optical bistability (OB) in semiconductor lasers biased from below to above threshold have been investigated theoretically. The OB result is found to be varied continuously from below to above threshold with its maximum value located just above threshold; this result has been verified experimentally.
