Femtosecond Lasers

Thorlabs offers a range of femtosecond laser sources for both free-space and fiber applications. For free-space applications, we offer the 1550 nm Femtosecond Fiber Laser, the 2 µm Femtosecond Fiber Laser featuring a pigtailed, FC/APC-terminated delivery fiber, the 1.3 µm to 4.5 µm Supercontinuum Laser, and the 3.5 µm to 11 µm Long-Wave IR Supercontinuum Laser.

A variety of accessories are available for use with femtosecond laser sources. Our supercontinuum generation kit spectrally broadens fs pulses near 800 nm. Our Femtosecond Autocorrelator and Femtosecond Pulse Compressors are recommended for use with Ti:sapphire lasers. The Microscope Slide Peak Power Sensor enables measurements of the relative peak power at the focus of a multiphoton microscope. Two THz antennas use a femtosecond laser input to generate THz radiation. We also offer optical delay lines, ultrafast optics, a dispersion measurement system, 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.
