Tunable Lasers

Thorlabs offers a selection of benchtop external cavity diode lasers with wide tuning ranges. First, our Tunable Laser Kits are modular systems that can be reconfigured for lasing at various wavelength. Their half butterfly gain chips and components can be purchased separately for customers who wish to modify their tunable laser kit's performance or to create their own tunable laser. We also offer the INTUN series of continuously tunable lasers, which are turnkey benchtop units. Lastly, we offer swept source lasers that are commonly used in swept source optical coherence tomography (SS-OCT).
