Abstract:

Semiconductor laser technology has shown to be a promising alternative to other laser technologies, e.g. solid state lasers, for employment in coherent satellite communication and fundamental physics applications. Being compact, robust, energy- and cost-efficient these semiconductor lasers fulfill the key mandatory requirements for deployment in space. At the Ferdinand-Braun-Institut, we have developed a versatile technology platform for integration of any two semiconductor chips, be they active (e.g. laser, amplifier) or passive (e.g. Phase modulator), in a fiber coupled laser module wherein all components are either space qualified or space compatible. Here we present a narrow linewidth high power laser module based on this platform that will be used in an iodine-based optical reference onboard a sounding rocket. We discuss its electro-optical performance. We further give an outlook on an ultra-narrow linewidth technology demonstrator laser module.
