About this technology
Overview
Previous non-planar ring oscillator (NPRO) designs have stability issues in terms of frequency, polarization, beam quality, mode choice, and output power due to the fact that the non-linear cavity design length prevents avoidance of spatial hole burning. Furthermore, large NPRO crystals are susceptible optical loss and not compatible with opto-mechanical parts and electro-optics developed for standard diode lasers.
