More than 100m Coherence Length Laser
Coherence length is defined as the distance over which the laser beam can travel without experiencing a phase discontinuity. This is a critical parameter in applications such as holography and interferometry where beams may be required be split with each leg going a long distance before being recombined. The coherence length is directly related to the linewidth of the laser. As a result, long coherence length lasers are almost exclusively single mode. Here at RPMC Lasers, we offer a wide range of diode-pumped solid-state (DPSS) lasers with a coherence length of more than 100m.
