Red lasers include DPSS laser (diode-pumped solid-state) and Diode laser. Typical wavelengths are 635, 650 and 670 nm. The shorter wavelengths have significantly better visibility for the human eye, but are more difficult to generate efficiently. Red laser diodes are often used for red laser pointer.The red lasers are based on our proprietary laser design technology. This laser technology allows our red lasers to operate in TEMoo mode with long coherence length and extremely low power consumption in a compact laser housing. CNI lasers have stabilized power, easy operation, reliable performance and long lifetime. The laser products include 3 series: high power and stability, low noise and single longitudinal mode laser. Free space or fiber-coupled (SM fiber, MM fiber, homogenization fiber) output available.
As the leading manufacturer and supplier in China, CNI is dedicated to offer best quality lasers , laser systems, High power laser, optical measuring equipment, Single longitudinal mode laser, laser processing equipment, High energy laser,machine vision and the photoelectric detection equipment.
