Benefits of technology

This technology allows for better control over both timing and frequency when sending signals through different types of light sources such as LED's or Lasers (LASER). It also improves upon existing methods used during transmission without affecting their performance.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the timing performance for precise and reliable lasers systems such as those described in UV/IR femtosecond spectroscopy and quantum cascade experiments. Specifically, it focuses on achieving highly precise and stable laser impulse times due to their relatively small differences caused by factors like temperature changes and other environmental influences over longer periods. However, current methods require large amounts of energy input and can result in instabilities with respect to timings.
