The Giant-chirp oscillator (GCO) can produce stable chirped pulses with large energies at low repetition rates, hence eliminating the need for a stretcher, pulse-picker, and one or more pre-amplifier stages from a typical chirped-pulse amplification system.

Wearable biomedical devices hold the promise of early detection, diagnosis, and treatment of a number of diseases. Because they are non-invasive, they have the potential to help patients and clinicians by providing continuous monitoring prior to the onset of more severe symptoms. These devices often.....
