Laser system for excitation of fluorescent light sources on a CubeSat

We have developed a compact fiber-coupled laser source emitting at 698 nm to excite a single-photon emitter in low Earth orbit. Built and qualified faster and cheaper compared to a traditionally certified payload, this system embodies the “new space” developing philosophy.
