TOPTICA offers complete laser systems as time saving and easy to use solutions for quantum technology. In optical clocks frequency combs are used as a clock work and to transfer the ultimate stability from the frequency of the best available lasers to the frequency of the clock. For low-noise microwave generation frequency combs are used to phase-coherently divide ultra-stable optical signals into the microwave domain. The high level of purity which can be achieved is very attractive for radar systems, telecommunications and time–frequency metrology. With its low-noise performance and unique robustness the DFC is the number one choice for these applications.  Other applications for which the DFC is well suited include Frequency Dissemination, High-Precision Spectroscopy, Dual- and Direct-Frequency comb Spectroscopy, Optical Sensing, Distance Measurements, Interferometry, Laser Noise Characterization and many more.
