- FC1500-ULNplus
The FC1500-ULNplus Ultra Low Noise Optical Frequency Comb brings the system performance to the next level. Additional hardware, optimized components and engineering ingenuity resulted in a perfect flywheel for transferring frequency stability between two or more user-defined frequencies at the 10−19 level. This exceeds the stability of any optical oscillator demonstrated to date, and transcends the stability requirement for optical clocks.
- Mid-IR
World-leading optical frequency comb technology is now available in the mid-infrared region. Taking advantage of Menlo Systems’ proprietary figure 9® modelocking technology, Menlo Systems’ difference frequency generation (DFG) based Mid-IR combs provide access to the 3-14 µm range. The reliable, turn-key mid-IR Comb is an enabling tool for applications in the important fingerprint region for high accuracy spectroscopy or nanoFTIR.
- FC1000-250
Frequency comb technology makes direct measurement of absolute optical frequencies possible. The FC1000 Optical Frequency Synthesizer is a compact, portable and flexible fiber-based femtosecond frequency comb system. The system is capable of providing at the same time a source for frequency metrology in both the visible and the near-IR regions (520-1040 nm) of the spectrum. A wide range of optional units enables us to tailor this versatile system to customer specific metrology solutions.
- SmartComb
SmartComb is an optical metrology system in a revolutionary compact package. In just 19” 3U it features the first fully automated turn-key optical frequency comb designed and built for use both in- and outside the optics lab. It measures your optical frequency anywhere between 630-2000 nm. Feed in your laser and get the frequency with 14 digits. Alternatively, it provides you with optical reference lines in the same spectral range (choose wavelength on ordering).
- FC1500-ULNnova
The FC1500-ULNnova is Menlo System’s latest optical frequency comb synthesizer for ultimate performance. The core of the new model consists of a redesigned comb oscillator, based on the patented ultra-low-noise (ULN) figure 9® mode locking technology. The enhanced design of this so-called “nova”-oscillator results in significantly improved robustness against acoustical distortion and thermal drift. The major benefit is a reduced free running linewidth of only 15 kHz.
