Congratulations to Last Year’s Winner: Bowen Li

 

Bowen Li

Postdoctoral researcher at the University of Colorado, Boulder, Bowen Li's winning proposal focuses on the first bidirectional all-normal dispersion (BANDi) fiber laser, a next-generation dual-comb laser source that generates two frequency combs from a single laser cavity. 


An Interview with Bowen Li

We spoke with Dr. Li regarding his exciting research, its impact on ultrafast science, and some of his future plans. Watch the video interview below, which was conducted by Marco Arrigoni of Coherent, Inc.

"This emerging dual-comb architecture demonstrates the feasibility of bidirectional mode-locking in fiber lasers using artificial saturable absorber and all-normal dispersion. Compared to existing dual-comb fiber lasers, it generates orders-of-magnitude-higher pulse energies as well as completely overlapping and flat optical spectra directly from the cavity."

2020 Winner: Dr. Bo Li

The 2020 Bernard J. Couillaud annual prize in ultrafast photonics was awarded to Dr. Bo Li, a postdoctoral researcher at Cornell University, is last year’s winner of the Bernard J. Couillaud Prize, presented on May 13, 2020. Bo Li’s research focuses on Multiphoton Imaging, a key application of ultrafast laser technology. His work has the potential to improve depths and speed of imaging, both critical to advances in neuroscience and disease studies.

About the Prize’s Namesake

A native of France, Bernard J. Couillaud earned his PhD in Laser Physics in 1978 at the University of Bordeaux and later completed a three-year visiting fellowship at Stanford University. Dr. Couillaud joined Coherent in 1983 and was instrumental in the development of numerous Dye, DPSS, and Ti:S lasers in his roles as Director of Engineering, Business Unit Manager, and Vice President of the Laser Group. Along the arc of this extraordinary academic and industrial career, he authored 65 publications and received numerous patents. He became President and CEO of Coherent in 1996, and served in that capacity until 2002. Dr. Couillaud was then Chairman of the Board of Directors until his retirement in 2007.

Dr. Couillaud gave more than a lifetime’s worth of dedication and achievements to physics, lasers, and photonics, and remains an inspiration to everyone that called him a friend, colleague, boss, or mentor. After his untimely death in 2017, Coherent and Optica (then OSA) partnered to create this award and honor his legacy by recognizing and financially supporting the next generation of innovators in photonics.
