Abstract
Multi-section laser systems are configured with a gain/modulation section and a pre-bias section. Both sections are electrically connected to a diode laser resonator and both sections are independently controllable via laser driver circuitry. The multi-section laser can be used to provide pulsing optimizations that include reducing the turn-on delay of the laser while also ensuring that the resulting laser light's spectral linewidth satisfies a threshold linewidth requirement. During use, a pre-bias current is applied to the pre-bias section. This current causes some photons to be spontaneously emitted. During this time, a gain current is refrained from being applied to the gain section until the resonator is seeded with a spectrum of photons from the pre-bias section. Once the resonator is sufficiently seeded, the gain current is applied to the gain section, thereby producing a seeded pulse of laser light having a desired spectral linewidth.
