    We describe a high-power extended-cavity laser which uses a multiple transverse mode laser as the gain medium and an intracavity single-mode fiber for mode stabilization. The laser delivers up to 30 mW to a single-mode fiber.

    A new type of laser structure which utilizes the selectively doped double-heterojunction (SDH) structure for lateral current injection (LCI) was proposed. A ridge waveguide AlGaAs/GaAs laser based on the SDH-LCI scheme was demonstrated to lase at the very low threshold current of 11.5 mA. The...

    The fabrication and performance characteristics of single frequency integrated external cavity distributed Bragg reflector lasers are described. The current is confined to the active region of these lasers using semi-insulating Fe-doped InP layers. The semi-insulating layer also provides lateral...

    Abstract. In a large-aperture KrF laser amplifier, steady-state gain is heavily reduced by intra-cavity amplified spontaneous emission (ASE). However, the reduced gain can be transiently enhanced by temporally suppressing the ASE with an intense depleting short pulse. Previously, we reported the...

    We report on new, simple and efficient multipass amplifiers using prisms or corner cubes to perform several passes in different planes of incidence. This scheme provides an optimised overlap between the signal passes and the pumped volume. We investigated our amplification geometry with Nd:YAG...
