More than 1m Coherence Length Lasers
Laser coherence length is defined as the distance over which the 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 to 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 laser diodes and DPSS lasers with a coherence length of more than 1m. We offer a selection of stabilization technologies like distributed feedback (DFB), distributed Bragg reflector (DBR), and volume Bragg grating (VBG) diode lasers. We also have temperature and current stabilized DPSS solutions to better fit your needs.
