Transient wavelength performance of 1.53 microm InP laser diodes for pumping of Er3+-doped solid-state lasers

The transient wavelength performance of high-power InP laser diode stacks with internal Bragg gratings is studied experimentally. Because of the wavelength selective nature of the internal grating, which is decoupled from the actual gain profile dynamics of the laser diode, the wavelength drift with respect to temperature and current is greatly reduced and steady-state conditions are reached after a short settling time of less than 50 ms.
