Frequency Stabilized HeNe Lasers
Both intensity stabilized and frequency stabilized options are available, using the time-proven design and fabrication process. Laser tubes suitable for this application are also now supported.
Frequency stability for long path difference interferometry, metrology, holography, spectroscopy and frequency marking. The short-term frequency stability of the laser makes it an excellent choice for interferometers with unequal arms. With the coherence length on the order of 100 m, the helium neon (HeNe) laser is ideal for large depth-of-field applications in holography and metrology. Frequency stability further enhances coherence length for critical measurements or exposures.
