Introduction

Steve Yifeng Cui is a prominent inventor based in Fremont, CA. He holds a total of 8 patents that showcase his contributions to the field of laser technology and optical systems. His work has significantly advanced the capabilities of laser modulation and defect ablation protection.

Latest Patents

One of his latest patents is titled "Laser closed power loop with an acousto-optic modulator for power modulation." This innovative system utilizes an acousto-optic modulator (AOM) to receive a laser beam and separate it into a primary beam and multiple diffracted beams based on an input signal. The power of the primary beam is directly influenced by this input signal. The system also incorporates a slit to transmit the primary beam while dumping the diffracted beams. Additionally, a controller generates a control signal based on feedback regarding the power of the primary beam, and a driver produces the input signal based on this control signal.

Another significant patent is "Systems and methods for advanced defect ablation protection." This invention involves directing a main beam and a leading beam toward a specimen using an optical arrangement with lenses. The main beam is incident on the specimen at a higher intensity than the leading beam. A TDI sensor captures electromagnetic radiation from both beam incidences, generating accumulated charge portions that are processed to yield valuable data.
