Accurate Frequency Laser's application for listing on the Sci-Tech Innovation Board has been accepted. In 2024, its market share in the global quantum technology sector is 9.21% for laser devices.

On December 8, Shanghai Pinzhen Laser Technology Co., Ltd. (referred to as "Pinzhen Laser") has submitted its application for IPO on the Shanghai Stock Exchange Science and Technology Innovation Board. China Securities Co., Ltd. is its sponsor institution, intending to raise 1.41 billion yuan. According to the prospectus, the company mainly focuses on the fields of quantum computing, quantum precision measurement, semiconductor domains such as wafer manufacturing, wafer testing, and wafer dicing, as well as cutting-edge research areas such as laser interference lithography and laser remote sensing. It has developed a new precision laser technology route, launching laser products with precise control of parameters such as wavelength, linewidth, noise, power, and pulse, which support the localization process of China's quantum technology and semiconductor industry chain. The company targets the demand for wide band, narrow linewidth, low noise, and high power precision lasers in the fields of quantum computing and quantum precision measurement. It generates low-noise precision seed lasers from fiber DFB seed sources or semiconductor seed sources, amplifies them with fiber amplifiers, and then uses nonlinear frequency conversion technology for frequency doubling, sum frequency generation, difference frequency generation, etc., to obtain lasers in any wavelength range from 177 to 5000nm, with low noise, narrow linewidth, high power, and tunability, and integrates optical functions such as laser frequency locking, splitting, combining, shifting, and switching according to customer requirements, serving domestic and foreign renowned universities, research institutes, and quantum technology companies such as customer A, Chinese Academy of Sciences, customer E, etc., supporting the rapid development of basic research and technological applications in the field of quantum technology. Additionally, the company's products are widely used in cutting-edge research areas such as laser interference lithography and laser remote sensing. Based on the urgent demand for domestically produced precision laser sources in the semiconductor industry, the company has launched precision laser products, serving important customers such as customer B, customer C, customer D, Zhongan Semiconductor, Angkun Vision, customer G, etc., promoting the localization process of wafer manufacturing equipment, testing equipment, and dicing equipment in China, achieving the replacement of imported laser light source products, which is of great significance for the stability of the semiconductor industry supply chain and the independent controllability of core technologies in China. After years of research and development, the company has developed a precise laser technology route of "seed source + fiber amplification + nonlinear frequency conversion + frequency stabilization", successfully realizing narrow linewidth, low noise, high frequency stability, and high power laser output covering the entire wavelength range from 177 to 5000nm. Compared with traditional semiconductor lasers and titanium sapphire lasers abroad, this solution has significant advantages such as anti-vibration, portability, and mode hopping, with some key performance indicators surpassing similar international products. With the superior performance parameters and high reliability stability of its precision laser products, the company fully meets the demand for precision light sources in the fields of quantum technology and semiconductors. According to the research data from QYResearch and calculations, by 2024, the company's market share in the global quantum technology laser market will be 9.21%, and its market share in the domestic quantum technology laser market will be 16.85%. In 2024, the company's revenue in the semiconductor field will be 75 million yuan, accounting for 1.98% of the domestic market share. Approved at the company's second extraordinary shareholders' meeting in 2025, after deducting issuance expenses, the raised funds will be invested in the following projects: In terms of finances, the company's operating income is about 80.4291 million yuan, 148 million yuan, 292 million yuan, and 180 million yuan in the years 2022, 2023, 2024, and January to June 2025, respectively. During the same period, the net profits are approximately 33.9629 million yuan, 60.4636 million yuan, 116 million yuan, and 70.9063 million yuan, respectively.
