MEMS-VCSEL Laser SourcesThe SL10 series of MEMS-VCSEL Swept-Wavelength Laser Sources, centered at 1060 nm, is available from Thorlabs Inc. with four different sweep rates ranging from 60 to 400 kHz.

Based on a patented microelectromechanical system (MEMS) tunable vertical cavity surface emitting laser (VCSEL), these light sources feature a coherence length of >100 mm and include an active power control that maintains constant output power over the lifetime of the laser. All drive electronics and trigger signals needed to seamlessly integrate these sources into custom swept-source optical coherence tomography systems are provided.

An output digital k-clock signal, generated by the integrated Mach-Zehnder interferometer and drive electronics, can be used as a data acquisition sampling clock with no further resampling in k-space required. The k-clock signal delay and maximum output power of the laser can be user adjusted up to ±8 ns and ±5%, respectively. All lasers are also available with an integrated matched balanced photodetector.
