Frequent and Accurate Laser, a company focusing on quantum technology fields such as quantum computing and precision quantum measurement, has submitted its application for IPO on the Science and Technology Innovation Board.

On May 22, Shanghai Pinzun Laser Technology Co., Ltd. (referred to as Pinzun Laser) applied for the change of IPO review status of Shanghai Stock Exchange Science and Technology Innovation Board to "submitted for registration". China Securities Co., Ltd. is its sponsor, and plans to raise 1.41 billion yuan. The prospectus shows that Pinzun Laser mainly focuses on quantum computing, quantum precision measurement and other quantum technology fields, wafer manufacturing, wafer quality inspection, wafer slicing and other semiconductor fields, as well as laser interference exposure, laser remote sensing and other cutting-edge scientific research fields. It has developed a new precision laser technology route, launched laser products with precise control of wavelength, linewidth, noise, power, pulse, etc., and supported the localization process of China's quantum technology and semiconductor industry chain. The company targets the demand for wide bandwidth, narrow linewidth, low noise, high power precision lasers in the fields of quantum computing and quantum precision measurement. It generates low noise precision seed laser using fiber DFB seed sources or semiconductor seed sources, amplifies power through fiber amplifiers, and then uses nonlinear frequency conversion technology to obtain 177-5000nm arbitrary wavelength, low noise, narrow linewidth, high power, tunable lasers. It also provides optical integration such as laser frequency locking, beam splitting, beam combining, frequency shifting, and switching to serve customers such as A, the Chinese Academy of Sciences, customer E and other domestic and foreign well-known universities, research institutions, and quantum technology companies, supporting the rapid development of basic research and technological applications in the field of quantum technology. In addition, the company's products are widely used in cutting-edge scientific research fields such as laser interference exposure and laser remote sensing. In the domestic market, in the field of quantum technology, the company's customers are mainly universities, research institutions, and quantum technology companies. The company mainly promotes the market through participation in optical industry exhibitions, referrals from old customers, continuity of existing business, proactive visits, advertising on well-known online platforms, etc., and timely feedback new technology or product requirements to the R&D department to help obtain new and old customer orders. In the semiconductor field, the company actively visits industry customers, promptly obtains customer needs, provides prototype trials according to customer needs, continues technical and product iterations, actively expands new business modules in the semiconductor industry chain, and obtains orders. In addition, the company's products have a certain degree of recognition in the industry, and some customers will actively consult the company for purchases. The company's customers mainly include universities, research institutions, quantum technology companies, and semiconductor equipment companies, such as customer A, customer B, customer C, customer D, Angkun Vision, the Chinese Academy of Sciences, etc. In the overseas market, the company mainly promotes through recommendations from downstream industry professionals, exhibition displays, etc. In recent years, through continuous expansion of the overseas market, the company's customer base has covered universities and research institutions in countries or regions such as the United States, Europe, Japan, and South Korea. During the reporting period, the company's main overseas customers are universities, research institutions, and quantum technology companies in the field of quantum technology, such as Harvard University, University of Colorado, University of Chicago, Stable Laser Systems, Inc., etc. After approval by the company's 2025 second extraordinary shareholders' meeting, the funds raised in this issuance will be invested in the following projects: Financially, in the fiscal years 2023, 2024, and 2025, the company achieved operating income of approximately 148 million yuan, 292 million yuan, and 418 million yuan respectively; during the same period, the net profit was approximately 60.46 million yuan, 116 million yuan, and 159 million yuan respectively.
