Substrate-transferred GaAs/AlGaAs crystalline coatings for gravitational-wave detectors: A review of the state of the art
G. D. Cole, S. Ballmer, G. Billingsley +16
In this Perspective we summarize the status of technological development for large-area and low-noise substrate-transferred GaAs/AlGaAs (AlGaAs) crystalline coatings for interferom…
Simultaneous Measurement of Mid-Infrared Refractive Indices in Thin-Film Heterostructures: Methodology and Results for GaAs/AlGaAs
Lukas W. Perner, Gar-Wing Truong, David Follman +5
We present our results for simultaneous measurement of the refractive indices of gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs) from $2.…
Mid-infrared supermirrors with finesse exceeding 400 000
G. -W. Truong, L. W. Perner, D. M. Bailey +9
For trace gas sensing and precision spectroscopy, optical cavities incorporating low-loss mirrors are indispensable for path length and optical intensity enhancement. Optical inter…
Passive Laser Power Stabilization via an Optical Spring
Torrey Cullen, Scott Aronson, Ron Pagano +8
Metrology experiments can be limited by the noise produced by the laser involved via small fluctuations in the laser's power or frequency. Typically, active power stabilization sch…
Watt-level widely tunable single-mode emission by injection-locking of a multimode Fabry-Perot quantum cascade laser
Paul Chevalier, Marco Piccardo, Sajant Anand +7
Free-running Fabry-Perot lasers normally operate in a single-mode regime until the pumping current is increased beyond the single-mode instability threshold, above which they evolv…
Single-mode instability in standing-wave lasers: The quantum cascade laser as a self-pumped parametric oscillator
Tobias S. Mansuripur, Camille Vernet, Paul Chevalier +13
We report the observation of a clear single-mode instability threshold in continuous-wave Fabry-Perot quantum cascade lasers (QCLs). The instability is characterized by the appeara…
