  Low noise lasers include DPSS laser (diode-pumped solid-state) and Diode laser. The noise issues of lasers are due to the competition of mode in laser resonant cavity, which lead to high frequency jitter of output power. Through special design for laser resonant cavity and other components, the laser amplitude noise can be reduce efficiently. CNI low noise laser can be widely applied to DNA sequency, cell sorting, spectrum analysis, interference measurement, laser holography, photo processing and biomedical and other fields.

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.
