German Rofin-Sinar Laser is the biggest developer and manufacturer of industrial CO₂ lasers, whose SM and Slab lasers are of the highest level of technology worldwide. Rofin-Sinar Laser is the one and only laser stock in NASDAQ.

The introduction of SM technololy is our another cooperation with Rofin-Sinar Laser Co.. As early as in 1993, we introduced the DC laser technology, which is the first cooperation between the two parties and has brought a big stride to China's CO₂ lasersmanufacturing level and has made our company become the biggest industrial CO₂ laser manufacturer in China.

Our second cooperation with Rofin-Sinar is about the introduction of its SM laser production technology and its management modules of quality control, check measurement, technical support, product standard and service specification, which will surely bring the strength of our company upward to a higher level.

SM lasers adopt computer control and switching supply excitation technology. Compared with DC-technology-based lasers, SM lasers feature better performance, lower cost, lower failure rate, more compacted construction, more powerful function and more flexible operation.

SM laser adopts an integrated structure of power supply and laser head, resulting in a big improvement of its transmission efficiency and reliability. Its performance effect is optimized with its flexible working modes of up to 64 options, the flexible combination of continuous wave, pulse and ultra-pulse modes, the free settingof pulse frequency and interval as well as the free setting of the power ascent and descent rates.
