A method for manufacturing hybrid optical coatings and hybrid mirror assemblies, including: a) providing a first optical coating having layers of alternating high and low refractive indices of crystalline materials on a first host substrate via an epitaxial growth technique; b) providing a second optical coating having layers of alternating high and low refractive indices of dielectric materials on a second host substrate via a physical vapor deposition (PVD) technique; c) directly bonding the first optical coating to the second optical coating; and d) removing the first host substrate.

Substrate-transferred stacked optical coatings

A method for generating a single-cavity dualcomb or multicomb for laser spectroscopy, the method comprising the steps of providing a laser system comprising a pump source, a gain medium, and a resonator having a spectral filter; spectrally filtering, by the spectral filter, light in the resonator and attenuating, in particular blocking, by the spectral filter, one or more wavelength bands at least one of which being located completely within the gain bandwidth of the laser system such that two or more at least partially separated spectral regions are provided; mode-locking the two or more at least partially separated spectral regions.
