Menlo Systems’ fiber-based femtosecond laser sources integrate the latest achievements in fiber technology into easy-to-use products. Menlo Systems’ unique figure 9® mode locking technology results in reproducible and long-term stable operation. The YLMO series with its all-PM design guarantees excellent stability and low-noise operation. As seed source for fiber amplifiers the oscillator is maintenance free, user installed and ready to use at the press of a single button. In the version with >2 W output power the laser is ideal for application in life sciences. In short: An OEM laser engineered for 24/7 operation.
