The authors demonstrate a two-dimensional optomechanical crystal cavity which traps a phonon mode within a phononic bandgap while yielding large thermal conductivity to the environment. High quantum cooperativity at millikelvin temperatures is realiz

Optomechanical systems offer new opportunities in quantum information processing and quantum sensing. Many solid-state quantum devices operate at millikelvin temperatures -- however, it has proven challenging to operate nanoscale optomechanical devic

The energy damping time in a mechanical resonator is critical to many precision metrology applications, such as timekeeping and force measurements. We present measurements of the phonon lifetime of a microwave-frequency, nanoscale silicon acoustic ca

We present the design and characterization of a quasi-two-dimensional optomechanical crystal cavity. At a refrigerated temperature of 10 mK, an intrinsic mechanical quality factor of 1.2 billion is observed and an effective quantum cooperativity grea

Using an optical probe along with single photon detection we have performed effective phonon counting measurements of the acoustic emission and absorption processes in a nanomechanical resonator. Applying these measurements in a Hanbury Brown and Twi

The design and operation of a 100 kW, 140 GHz pulsed gyrotron are reported. To our knowledge, this is the highest frequency at which high gyrotron output power (>-100 kW) has been achieved. Results are presented for gyrotron operation in the range of

The design and construction of a pulsed 100 kW, 140 GHz gyrotron will be described. Initial gyrotron operation is expected in late 1981 or early 1982. Advances in gyrotron theory carried out in support of this experimental research will also be descr
