Weikuai Photonics raises tens of millions of yuan to build China's own ultrafast lasers
What's the deal? Beijing Weikuai Photonics Technology raised a new round of tens of millions of yuan, backed by Guojing CapitalDealroom has a profile for this one. Try Dealroom → — the private fund arm of Jiangsu Guojing Holding Group — and Weichi Capital. The company develops fibre-based ultrafast lasers for scientific instruments, medical devices, and precision manufacturing.
What's the endgame? Weikuai wants to build a domestic "heart" for high-end equipment: the ultrafast laser. It says it has cut full-system laser costs by 30% to 40% through a redesigned technical architecture, and offers a flexible power-transmission cable to ease integration for downstream equipment makers.
Why now? Demand for stable industrial-grade ultrafast lasers is widening as semiconductor advanced packaging and through-glass-via drilling scale up. Weikuai's high-power 780nm femtosecond laser already runs around the clock on a co-packaged optics (CPO) line at a leading manufacturer.
By the numbers: Weikuai's 2025 revenue grew more than 70% year on year. Media reports put that revenue above US$2.75M and say the company turned a profit — figures worth noting as the business moves from R&D toward commercial scale.
The company's track record stretches to orbit: in April 2023, less than three years after its founding, Weikuai supplied a domestically made 780nm femtosecond laser to China's space station, built to survive launch shock, vibration, and temperature swings.
Why it matters to the investor: Guojing Capital called the deal "an important move" to back core components for high-end equipment and support self-controllable hard tech (translated from Chinese). It plans to connect Weikuai with Yangtze River Delta resources in biopharma and semiconductors.
The signal: The round targets a weak link in China's push for domestic high-end light sources, where imports still dominate scientific-grade and specialist-wavelength products. But with the amount, valuation, and lead investor undisclosed, the sharper story is a research-led maker starting to find paying customers — not a shift in the competitive landscape.
