Single frequency/SLM laser

CNI Laser manufactures compact diode-pumped solid-state DPSS single frequency lasers/single longitudinal mode lasers with narrow spectrum linewidth and long laser coherence length. The diode-pumped lasers are based on our proprietary laser cavity technology. The proprietary technology allows the lasers to operate in a single longitudinal mode and TEM00 mode with low amplitude noise and extremely low power consumption in a compact laser housing. The single frequency laser is a single longitudinal mode operation. The single frequency lasers are for industrial instrumentation applications in Raman spectrum scopy, holography, biomedical, fluorescence, reprographics, interferometry, semiconductor inspection and remote detection.


CNI Laser now provides 532 nm high power single longitudinal mode laser up to 5W and 1064 nm lasers up to 10W. You can choose the single longitudinal mode laser with other wavelength based on the following tables.

Single Longitudinal Mode Lasers
Wavelength: 360nm, 457nm, 473nm, 532nm, 556nm, 561nm, 589nm, 656.5nm, 660nm, 671nm, 720nm, 1064nm, 1319nm, 1342nm
