... . They feature diffraction-limited, high-brightness, astigmatism corrected gaussian beams with M2 values of <1.2. Depending on the application and coherence length requirements, a diode laser module may be the perfect choice to replace your HeNe laser. Diode laser modules are smaller, require less ...

... since this reduces the effects of the environment (e.g., vibration). Ample illumination power is a good solution. Narrow laser linewidths/long coherence lengths are essential when there are large pathlength differences. Variation in the laser frequency during holographic recording shifts the interference ...
