Red Single Frequency Laser

In addition to narrow linewidth and long coherent length, the frequency stabilized single frequency laser/narrow linewidth laser has the advantages of stable frequency and low frequency noise,etc.All solid state single longitudinal mode red laser at 639nm is made features of ultra compact, long lifetime, low cost and easy operating, which is used in DNA sequencing, flow cytometry, cell sorting, optical instrument, spectrum analysis, interference, measurement, holography, physics experiment, etc. 111Features            Ultra narrow linewidth : spectral linewidth <0.00001 nm Ultra low noise : Noise of amplitude <1% Long coherent linewidth : coherent linewidth >50m Fiber coupled optional Frequency stabilized laser optional Modulation repetition rete u…
