Description

Menlo Systems’ fiber-based femtosecond laser sources integrate the latest achievments in fiber technology into easy-to-use products. Menlo Systems’ unique figure 9® design results in reproducible and long-term stable operation. It is based on the well-established nonlinear optical loop mirror (NOLM) mode locking mechanism. Both oscillator and amplifier use polarization maintaining (PM) fiber components only, ensuring excellent stability and low-noise operation. The subsequent second harmonic generation for the 780 nm is a highly efficient module for maximum performance.The laser is maintenance free, user installed and ready to use at the press of a single button. Customize your laser with the available options to match the requirements of your application.
