text: Precision sensing and manipulation of milligram-scale mechanical oscillators
has attracted growing interest in the fields of table-top explorations of gravity
and tests of quantum mechanics at macroscopic scales. Torsional oscillators present
an opportunity in this regard due to their remarked isolation from environmental
noise. For torsional motion, an effective employment of optical cavities to enhance
optomechanical interactions—as already established for linear oscillators—so far
faced certain challenges. Here, we propose a concept for sensing and manipulating
torsional motion, where exclusively the torsional rotations of a pendulum are
mapped onto the path length of a single two-mirror optical cavity. The concept
inherently alleviates many limitations of previous approaches. A proof-of-principle
experiment is conducted with a rigidly controlled pendulum to explore the sensing
aspects of the concept and to identify practical limitations in a potential state-of-the
art setup. Based on this study, we anticipate development of precision torque
sensors utilizing torsional pendulums that can support sensitivities below 10−19Nm/√Hz,
while the motion of the pendulums are dominated by quantum radiation pressure
noise at sub-microwatts of incoming laser power. These developments will provide
horizons for experiments at the interface of quantum mechanics and gravity.

text: We unveil a powerful method for the stabilization of laser injection locking
based on sensing variations in the output beam ellipticity of an optically seeded
laser. The effect arises due to an interference between the seeding beam and the
injected laser output. We demonstrate the method for a commercial semiconductor
laser without the need for any internal changes to the readily operational injection
locked laser system that was used. The method can also be used to increase the
mode-hop free tuning range of lasers, and has the potential to fill a void in
the low-noise laser industry.

text: "We build a parametric amplifier with a Josephson field-effect transistor
(JoFET) as the active element. The resonant frequency of the device is field-effect
tunable over a range of 2 GHz. The JoFET amplifier has 20 dB of gain, 4 MHz of
instantaneous bandwidth, and a 1-dB compression point of -125.5 dBm when operated
at a fixed resonance frequency.\r\n\r\n"
