Dr. Haynes Pak-Hay Cheng

Responsible for daily operation, including sales, internal bookkeeping, and team management. Brought finances to stable ground and eventually to growth that supports new product developments and new hirings. Lead a talented team to deliver state-of-the-art timing distribution solutions worldwide. Acquired installations at all major free electron laser facilities around the world. Cycle became the world leader in timing distribution solutions, and expanded its product line into other exciting areas.

Lead a team of 10 engineers and scientists to deliver China's first fully automated pulsed optical timing distribution system. Delivered project on-time and on-budget. Ensured first reference customer was fully satisfied with the delivered products. Secured follow-on contracts with customer to expand the timing system, enabling it to support even more timing links.

Responsible for the development of microchip Q-switched lasers and picosecond MOPA laser systems for industrial laser machining applications. Reliability and long-term testing of prototypes. Advised on electronics design, troubleshooting, and FPGA development. Designed and assembled prototypes that require fiber splicing, electronics troubleshooting, temperature stabilization, and opto-mechanical designs. Supervised entry-level engineers/scientists to support R&D efforts.

Created prototypes of various optical-RF, and optical-optical timing detector, with femtosecond timing resolution, based on heterodyne detection. Designed optical layout and opto-mechanics assemblies using Solidworks. Worked with Thorlab’s in-house machine shop to produce opto-mechanic components. Designed and built analog electronics circuits, PCB layouts, microprocessor programming, and automated data acquisition. Brought projects to completion on tight schedules and within budget.

Helped commercialize a high-efficiency closed-cycle Helium recovery system with an OEM customer. Worked with various suppliers, contractors, notified certification bodies and OEM customer to bring product to market.

Assembled and tested electronic sensors and programmable logic controllers, tested cryostats and helium liquefiers, designed simple mechanical components, and sourced parts from suppliers. Assisted with customer liaison – provided sales quotation, project specification, technical design and project planning.

Studied quasi-three-level diode-pumped solid-state (DPSS) Q-switched lasers. Investigated timing jitter in passively synchronized Q-switching. In collaboration with Lund University Hospital, took part in autofluorescence imaging of skin lesions using a frequency-tripled 355 nm Q-switched laser.
