Demanding diode lasers as Distributed Feedback (DFB) Diode Lasers or External Cavity Diode Lasers (ECDLs) require a highly precise, low noise, long term stable diode laser controller. Spectral linewidth as well as long term stability of these laser systems are directly determined by the laser controller. The PilotBFY represents more than 15 years of experience in precision laser system development for laboratory and industrial environments.
