ECDL / DFB Lasers

External cavity and distributed-feedback diode lasers

Tunable single-frequency diode lasers consist of a laser diode and a frequency selective element like a grating, which controls the emission frequency. TOPTICA offers diode laser systems with an external grating (ECDL) as well as systems with a frequency-selective element integrated within the semiconductor structure itself (DFB diodes). These systems are available for individual wavelengths and provide tunable, narrow-linewidth emission.
