Thorlabs announces MEMS‚ÄêVCSEL Swept‚ÄêWavelength Laser Sources

August 16, 2018 – Thorlabs announced that it has released versions of its 1300 nm MEMS‚ÄêVCSEL Swept‚ÄêWavelength Laser Sources. With a coherence length of over 100 mm and sweep rates of either 100 kHz or 200 kHz, the SL131090 and SL132120 are commercially available MEMS‚ÄêVCSEL laser sources. Based on a patented microelectromechanical system (MEMS) tunable vertical cavity surface emitting laser (VCSEL), these light sources include an active power control that maintains constant output power over the lifetime of the laser.

All drive electronics and trigger signals needed to integrate these sources into custom swept‚Äêsource OCT systems are provided. An output digital “k‚Äêclock” signal generated by the integrated Mach‚ÄêZehnder interferometer (MZI) and drive electronics can be used as a data acquisition sampling clock, with no further resampling in k‚Äêspace required. The k‚Äêclock signal delay and maximum output power of the laser can be user adjusted up to ±8 ns and ±5%, respectively.
