Asynchronous mid-infrared broadband optical parametric oscillator for dual-comb spectroscopy

EPJ Web of Conferences, 2013
Two asynchronous, broadband 3.3-μm pulse trains with a stabilized repetition-rate difference of up to 5-kHz were generated from a single optical parametric oscillator. With additional carrier-envelope-offset stabilization, it could be applied to coherent

Low-cost, in-liquid measuring system using a novel compact oscillation circuit and quartz-crystal microbalances (QCMs) as a versatile biosensor platform [PDF]

Journal of Sensors and Sensor Systems, 2017
Quartz-crystal microbalances (QCMs) are commercially available mass sensors which mainly consist of a quartz resonator that oscillates at a characteristic frequency, which shifts when mass changes due to surface binding of molecules.

Recent progress in the performances of ultrastable quartz resonators and oscillators

International Journal for Simulation and Multidisciplinary Design Optimization, 2016
Stressed compensated (SC) cut led recently to the best frequency stability ever obtained with a quartz oscillator, 2.5 × 10−14 for the flicker frequency modulation (FFM) floor. This result is confirmed in this paper with a 3.2 × 10−14 ± 1.1 × 10−14.

Stability of a chain of phase oscillators

Physical Review E, 2011
We study a chain of N+1 phase oscillators with asymmetric but uniform coupling. This type of chain possesses 2(N) ways to synchronize in so-called traveling wave states, i.e., states where the phases of the single oscillators are in relative equilibrium. We show that the number of unstable dimensions of a traveling wave equals the number of oscillators

Carrier-envelope Phase Drift Detection of Picosecond Pulses

EPJ Web of Conferences, 2013
A bandwidth-independent, linear and scalable method for carrier-envelope phase drift measurement demonstrated. Our experiments reveal that carrier-envelope phase drift of a picosecond pulse train can be directly obtained from the spectrally resolved ...

Sub-kHz linewidth intracavity VECSEL-pumped OPO [PDF]

APL Photonics
We report low noise and narrow linewidth performance of an actively stabilized optical parametric oscillator, intracavity-pumped by a visible AlGaInP-based vertical-external-cavity surface-emitting laser (VECSEL). Under dual-locking conditions, where the
