Optimization of acousto-optic optical frequency combs
Acousto-optic optical frequency combs can easily produce several hundreds of mutually coherent lines from a single laser, by successive frequency shifts in a loop containing an acousto-optic frequency shifter. They combine many advantages for multi-heterodyne interferometry and dual-comb spectroscopy.

Integrated dual optical frequency comb source
A monolithically integrated dual-channel optical frequency comb source is demonstrated in this paper. Three lasers are integrated on a single chip using a regrowth-free fabrication process in a master-slave-slave configuration. The master laser’s power is split equally using a 1x2 multimode interference coupler and injection locks the two slave lasers.

Microresonator frequency comb optical clock
Optical-frequency combs enable measurement precision at the 20th digit, and accuracy entirely commensurate with their reference oscillator. A new direction in experiments is the creation of ultracompact frequency combs by way of nonlinear parametric optics in microresonators.

Precision Phase Control of an Ultrawide-Bandwidth Femtosecond Laser: a Network of Ultrastable Frequency Marks across the Visible Spectrum [PDF]
We demonstrate that the stability of the current optical frequency comb generated by a Kerr-lens mode-locked femtosecond laser is limited by the microwave reference used for phase locking the comb spacing.

Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy
Optical frequency combs represent a breakthrough in the field of metrology. Because an optical frequency comb has a large number of comb modes, the optical energy is dispersed over the comb modes, and the optical energy per comb mode is very small.
