High-Power Picosecond and Femtosecond Lasers from 515 to 1970 nm – Rainbow HP

Rainbow HP Series from NPI Lasers

The Rainbow HP series comprises high-power picosecond and femtosecond laser systems covering wavelengths from 515 nm to approximately 2 µm. Depending on the model, the lasers provide average output powers from more than 200 mW to more than 5 W, with pulse durations below 10 ps or as short as 150 fs.

The series includes frequency-converted visible systems as well as high-power sources around 780 nm, 1 µm, 1.55 µm and 2 µm. This allows users to select a source according to wavelength, pulse duration, average power and application requirements.

Rainbow HP lasers are designed as fully integrated, turn-key systems for scientific and industrial applications including microscopy, spectroscopy, nonlinear optics, terahertz generation and photonics research.
