Three projects such as MOPA-ns laser technology passed the evaluation of scientific and technological achievements
[ Instrument Network Instrument Development ] On September 9, 2019, Zhongke Hechuang (Beijing) Science and Technology Achievement Evaluation Center organized an expert to hold the "AONANO-XP series MOPA-ns laser completed by Inno Laser Technology Co., Ltd. in Beijing. Technology and other three projects scientific and technological achievements evaluation meeting.
Founded in 2011, Inno Laser Co., Ltd. is a national high-tech enterprise headquartered in Nanshan District Science and Technology Park, Shenzhen. It specializes in the research, development, production and sales of lasers in the field of micro-machining and provides customized products in the form of laser modules. Processing solutions. The company is one of the few industrial laser manufacturers in the world with the core technology and production capacity of nanosecond, sub-nanosecond, picosecond, femtosecond micromachining lasers. It is one of the few manufacturers in the world to supply industrial deep-UV nanosecond lasers. . Products include DPSS Q-switched nanosecond lasers, ultrashort pulse (picosecond, femtosecond) lasers and MOPA (nanosecond/sub-nanosecond) lasers, ranging from infrared to deep ultraviolet, from nanoseconds to femtoseconds. Pulse width.
The expert group reviewed the technical information provided by the technical party, listened to the technical research report, and formed relevant opinions after questioning, answering questions and discussions.
Among them, "AONANO-XP series MOPA-ns laser technology" provides the technical information is basically complete, in line with the scientific and technological achievements evaluation requirements; the technology design and use the main oscillator power amplification (MOPA) structure of the fiber laser, output linear polarization infrared, and Nanosecond pulse converted into green light, ultraviolet to deep ultraviolet, beam quality M2 less than 1.2, pulse width 100ps~5ns adjustable, pulse repetition frequency 10kHz~2MHz optional, peak power greater than 25kW; fiber optic structure in MOPA structure The laser uses a self-developed multi-pass fiber amplifier to obtain a nanosecond output of 1064 nm @ 1 MHz infrared light with an average power of over 120 W. It has been applied in fields such as solar energy; the technology has obtained a number of patents. The expert group agreed to pass the evaluation of scientific and technological achievements, and the overall technology has reached the international advanced level.
The AOPICO series of high-power UV picosecond lasers provide a complete range of technical data to meet the requirements of scientific and technological achievements. This technology uses SESAM mode-locking technology to generate picosecond pulses in optical fibers, amplify based on MOPA structure, and then pass through solid-state amplifiers and nonlinear conversion. Module, output high-energy picosecond pulse in ultraviolet band, beam quality M2 is less than 1.2, pulse repetition frequency from single pulse to 1.5MHz, average power 35W@800kHz; this technology is designed and adopted fiber seed source, solid state amplification technology, both The technical advantages of both. At the same time, a high-speed circuit and related software with a working frequency higher than 1MHz are designed independently, and the output pulse energy of the laser does not change with the change of the operating frequency. It has been applied in the fields of consumer electronics; the technology has applied for a number of patents. The expert group agreed to pass the evaluation of scientific and technological achievements, and the overall technology has reached the international advanced level.
The technical data provided by the FORMULA series of high-power UV nanosecond laser technology projects is basically complete, in line with the requirements of scientific and technological achievements evaluation; this technology uses the intracavity triple frequency technology to achieve an ultraviolet laser output with an average power higher than 30W, from infrared to ultraviolet. The energy conversion efficiency is close to 50%; the technology uses self-designed laser cavity, temperature control technology, and high-speed signal processing based on FPGA, so that the laser has a beam quality M2 less than 1.2, the spot roundness is greater than 95%, and the pulse peak power is stable. The property is less than 2% (rms) and the 12-hour average power stability is less than 0.5% (rms). Applied in the field of consumer electronics; the technology has obtained a number of patents. The expert group agreed to pass the evaluation of scientific and technological achievements, and the overall technology has reached the international advanced level.
