Red Laser

CNI manufactures compact diode-pumped solid-state DPSS blue laser and blue diode laser products including air-cooled CW red laser, low noise red laser, single longitudinal mode red laser (single frequency red laser) and air-cooled and water-cooled Q-switched red laser systems.


For single longitudinal mode lasers (single frequency lasers) are ideal for applications requiring extremely long temporal coherence and an extremely narrow spectral linewidth. These lasers are commonly used for various scientific purposes such as holography, interferometry, biological experiments, communications research, and a broad spectrum of other applications.


CNI also has low noise red lasers, which are ideal for applications requiring less than 1% noise. Most of them are used for fluorescence excitation, PIV, Raman Spectroscopy, and a broad spectrum of other applications.


The Q-Switched red lasers are ideal for applications requiring the highest available peak power and single pulse energy, also the short pulse width, which have a broad applications in the industry.
