Two-channel interferometer based on inter-laser detection of reflected radiation

New modality in optical microscopy based on laser with injected radiation

“…As concerns the speed of measurements it depends on cavity bandwidth, laser excitation and coupling between the generated fields [18,19]. This parameter can be easily measured with the help of injected radiation regime.…”

“…Usually, this effect is unwanted, and special precautions are taken to avoid it. However, analysis has shown that a laser with injection of external radiation can serve as a sensitive informative detector of this radiation [11][12][13][14][15][16][17][18][19][20]. Injected light has a considerable influence on laser amplitude and frequency parameters [15][16][17][18].…”

The character of this effect depends on the surface properties of an external reflector and its location.…”
