Femtosecond Lasers

Thorlabs' femtosecond lasers consists of both free-space and fiber-pigtailed lasers. For free-space applications, we offer the Octavius® Ti:Sapphire Laser, Tiberius® Tunable Ti:Sapphire Laser, Y-Fi™ Femtosecond Ytterbium Fiber Laser, Y-Fi™ Optical Parametric Amplifier (OPA), the 1.3 µm to 4.5 µm Supercontinuum Source and the 1550 nm Femtosecond Fiber Laser. Completing this laser family is the 2 µm Femtosecond Fiber Laser, which features a pigtailed, FC/APC-terminated delivery fiber.

A variety of accessories are available for use with femtosecond laser sources. Our Femtosecond Autocorrelator and Femtosecond Pulse Compressor are recommended for use with our Ti:sapphire lasers. Our supercontinuum generation kit spectrally broadens fs pulses near 800 nm. We also offer ultrafast optics, a dispersion measurement system, optical delay lines, and dispersion-compensating fiber.

Menlo Systems, a strategic partner of Thorlabs, offers several fiber-based femtosecond laser systems. These systems are capable of pulse widths in the tens of femtoseconds with wavelengths in the visible and IR. Menlo Systems' lasers are commonly used for high-speed spectroscopy, optical metrology, and attosecond pulse generation.
