Gathering in Qingdao | The 8th Academic Annual Conference for Young Optical Scientists
2025-09-29
From September 26 to 29, 2025, the 8th Annual Academic Conference for Young Optical Scientists, organized by the Chinese Journal of Lasers and supported by the 3rd Youth Editorial Committee, was successfully held in Qingdao! This conference Designed to provide a high-quality exchange platform for young optical scientists—both domestic and international—to advance their careers in optical science and technology, the conference features 12 thematic sessions that delve into cutting-edge research topics and core technologies across various fields of optics. Simultaneously, it showcases groundbreaking scientific achievements while fostering collaborative academic exploration, creating a vibrant spectacle where modern technology and scholarly pursuits seamlessly intertwine.
Hunan Haomin Optoelectronics, as a sponsor of this conference, showcased its booth as another major highlight of the event, drawing numerous young optics professionals to stop by and learn more. Through on-site explanations, interactive experiences, and product demonstrations, the company delivered a fresh visual and experiential journey to all attendees. Let’s take a look at some photos from the exhibition!
This time, attendees were shown Single-frequency fiber lasers, GHz-repetition-rate-locked femtosecond optical combs, asynchronous optical sampling sources, and more Series of optoelectronic products:
GHz-repetition-rate femtosecond laser : Center wavelength of 1560 nm, with a 3dB bandwidth exceeding 10 nm, an 8-hour repetition rate drift of less than 2 kHz, and pulse width below 300 fs. The output power can reach up to 1 W. Featuring a fully polarization-maintaining fiber design and fundamental frequency mode-locking, the repetition rate is customizable between 800 MHz and 2.5 GHz. Additionally, its unique cavity design ensures long-term stability of the laser even under external environmental disturbances, making it ideal for applications such as terahertz technology, electromagnetic spectrum channelization, femtosecond ranging, high-precision long-distance time and frequency transfer, and precision manufacturing.
All-locked optical frequency comb : Featuring high repetition rate, ultra-high stability, and environmental insensitivity, this system employs a fully polarization-maintaining fiber NALM mode-locked femtosecond fiber seed source combined with low-noise femtosecond fiber amplification technology, achieving exceptionally low phase noise. It delivers a 3dB spectral width exceeding 30nm and can be configured with an ultra-continuous spectrum module covering the 1000–2000nm range, enabling a maximum repetition rate output of up to 250 MHz.
Asynchronous Optical Sampling Source We can provide two high-coherence pulse trains with tunable repetition-rate differences, delivering highly stable femtosecond pulse sequences. Since these two pulse trains feature pulses with a minute repetition-rate offset, they exhibit exceptional coherence properties, enabling high-speed asynchronous sampling of low-speed pulses. This unique sampling approach significantly enhances measurement accuracy, making it ideal for advanced applications such as laser ranging, THz spectroscopy, spectral detection and metrology, as well as high-temperature field measurement and imaging.
Insight into the future of optoelectronics, forging ahead with determination. Through this in-depth exchange with industry professionals in the optoelectronics field, we’ve gained a deeper understanding of industry trends and technological breakthroughs, paving the way for new opportunities in Haomin Optoelectronics’ business expansion. Looking ahead, Haomin Optoelectronics will continue to focus on the R&D and innovation of precision optical measurement instruments, guided by our core philosophy: "Strive for excellence, create value, and remain committed to innovation." We are dedicated to delivering globally stable, high-performance laser sources with ultra-narrow linewidths, femtosecond lasers, and optical frequency comb products to customers worldwide. Additionally, we’ll provide tailored solutions for cutting-edge applications such as optical atomic clocks, terahertz generation, high-precision distance measurement, fiber-based time and frequency transfer, quantum communication, and coherent beam combining.
