Haomin Optoelectronics showcases its time-and-frequency precision instruments at the 2025 National Conference on Time and Frequency.
2025-10-20
Conference Background
From October 16 to 19, China's largest and most prestigious academic event in the field of time and frequency—the 19th National Conference on Time and Frequency—was held in Xinjiang. This year’s conference was centered around the theme "Leading Innovation in Time and Frequency, Solidifying the Foundation for a Strong Nation." It brought together cutting-edge discussions on key topics such as atomic clocks, Universal Time, timekeeping and time dissemination, quantum precision measurement, and the ongoing transformation of the International System of Units. Through a series of high-profile invited talks, vibrant sub-session discussions, and dynamic paper presentations, the conference comprehensively showcased China’s remarkable breakthroughs and significant achievements in the time and frequency domain over the past two years.
A variety of "time and frequency" products, including the all-locking optical frequency comb, make their debut.
Traveling over 3,000 kilometers to attend this grand event, Haomin Optoelectronics sincerely showcased a range of "time and frequency" products to the audience, including dual optical combs, GHZ-repetition-rate-locked femtosecond optical combs, and fully locked optical frequency combs.
Among them, Haomin Optoelectronics' independently developed high-stability femtosecond repetition-rate-locked optical comb features advanced technologies such as a fully polarization-maintaining femtosecond fiber seed source, low-noise femtosecond fiber amplification, a high-speed phase-locked loop, and intelligent repetition-rate locking—enabling one-click automatic locking of the repetition rate while ensuring stable operation across the entire temperature range. Additionally, its unique cavity design guarantees long-term reliability and consistent performance of the laser under various environmental conditions. Another core precision product, the fully locked optical frequency comb, integrates a fully polarization-maintaining NALM-mode-locked femtosecond fiber seed source paired with low-noise femtosecond fiber amplification technology, delivering ultra-low phase noise and achieving a 3dB spectral width exceeding 30nm. It can also be configured with an ultra-continuous-spectrum module covering the 1000–2000nm range. Furthermore, the newly upgraded control system ensures even greater operational stability, supporting repetition rates of up to 250 MHz.
Precision instruments drew numerous attendees to stop and engage in conversation.
This conference not only showcased a wide range of precision time and frequency measurement products, but also drew numerous attendees to stop and engage in discussions with Haomin Optoelectronics, whose high-stability, high-performance narrow-linewidth lasers, ultrashort-pulse lasers, photodetectors, frequency synthesizers, and other advanced optoelectronic products were on display.
