Menlo Systems’ Ytterbium based femtosecond fiber laser oscillator integrates the latest developments in fiber technology and incorporates these enhancements into an easy-to-use product.

Our patented figure 9® technology delivers reliable and consistent mode-locking, which is ideally suited to ensure long-term stable operation. The PM-fiber design guarantees excellent stability and low noise, even in harsh environments with high fluctuations in temperature. As a seed source for amplifiers, the YLMO offers easy integration and maintenance-free operation, engineered for 24/7 operation.
