Abstract
Apparatus, systems, and methods of generating multi combs can be used in a variety of applications. In various embodiments, a passive resonator can be disposed in the laser cavity of a mode-locked laser to generate a nested frequency comb. The passive resonator can be a sample under investigation, where a characteristic of the sample is determined using the generated nested frequency comb. Additional apparatus, systems, and methods are disclosed.
Claims8
A system comprising:
- a mode-locked laser cavity having a cavity length;
- a sample mount disposed in the mode-locked laser cavity such that a sample arranged as a passive resonator inserted in the mode-locked laser cavity via the sample mount is operable in conjunction with a laser beam of the mode-locked laser cavity to generate a nested comb having multiple frequency combs;
- and
- a spectrum analyzer disposed to operably receive the multiple frequency combs;
- and
- a processor coupled to the spectrum analyzer to operatively determine a characteristic of the sample based on the multiple frequency combs operably received by the spectrum analyzer.
