Abstract :
The performance of a delay line discriminator dedicated to the characterization of high spectral purity lasers is investigated. The system noise floor is obtained using a symmetrical delay. The vibrations are one of the main problems with this approach at the low frequency offsets. However, the system is able to characterize commercially available narrow linewidth lasers, such as external cavity lasers and fiber lasers.
