Menlo Systems’ YLMO Mid-IR femtosecond fiber laser integrates the latest developments infiber technology and incorporates these enhancements into an easy-to-use product.
The YLMO Mid-IR with its compact and robust design guarantees excellent stability and consistent long-term performance. The power levels of more than 100 mW easily serve common
requirements of state-of-the-art mid-IR applications. Femtosecond pulse durations of less than
400 fs allow broadband spectroscopy applications as well as time resolved measurements.
The maintenance free operation guarantees a worry-free device that enables our customers tofocus their time and resources on their actual application. The installation of the laser system isas easy as it gets, taking only a few minutes.

Starting from Menlo’s turn-key, reliable figure 9® fiber laser oscillators, a two-color femtosecond laser system is realized using spectral shifting in highly nonlinear fibers. The two branchesof femtosecond pulses of different wavelengths are spatially and temporally overlapped and subsequently focused into a nonlinear crystal for difference frequency generation (DFG).This
allows the generation of femtosecond pulses in the mid-IR covering the spectral range from 3 μm to 5 μm with high output power levels. The wavelength can be fully automated tuned in thespecified wavelength range.
