Publication number: 20240079843Abstract: Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument. The mode-locked laser can produce sub-50-ps optical pulses at a repetition rates between 200 MHz and 50 MHz, rates suitable for massively parallel data-acquisition. The optical pulses can be used to generate a reference clock signal for synchronizing data-acquisition and signal-processing electronics of the portable instrument.Type: ApplicationFiled: November 8, 2023Publication date: March 7, 2024Applicant: Quantum-Si IncorporatedInventors: Jonathan M.

Publication number: 20240068943Abstract: Instrument control and data acquisition in advanced analytic systems that utilize optical pulses for sample analysis are described. Clocking signals for data acquisition, data processing, communication, and/or other data handling functionalities can be derived from an on-board pulsed optical source, such as a passively mode-locked laser. The derived clocking signals can operate in combination with one or more clocking signals from a stable oscillator, so that instrument operation and data handling can tolerate interruptions in operation of the pulsed optical source.Type: ApplicationFiled: November 2, 2023Publication date: February 29, 2024Applicant: Quantum-Si IncorporatedInventors: Jonathan M. Rothberg, Benjamin Cipriany, Faisal R. Ahmad, Joseph D. Clark, Daniel B. Frier, Michael Ferrigno, Mel Davey, Thomas Raymond Thurston, Brett J. Gyarfas, Todd Rearick, Jeremy Christopher Jordan

Publication number: 20220329037Abstract: Disclosed herein are aspects of an optical pulse stretcher for temporally stretching a short duration pulsed light signal to reduce its peak power, thus reducing the risk of causing damage to components that receives the pulsed light signal. Some embodiments are directed to a molecule sequencing system, in which photochemical damage caused by laser pulses having high peak power may be mitigated by the optical pulse stretcher. In one embodiment, the optical pulse stretcher comprises a polarizing beam splitter, a quarter-wave plate and a single etalon disposed in series. In another embodiments, an optical pulse stretcher splits a pulsed light signal along multiple delay lines before combining the split signals together to form a stretched light signal.Type: ApplicationFiled: April 12, 2022Publication date: October 13, 2022Applicant: Quantum-Si IncorporatedInventors: Michael Bellos, Faisal R.
