Abstract
The relative optical frequency stability of a narrow bandwidth lithium niobate optical holographic filter stabilized laser in comparison with an optical reference unit at 1547.825 nm was examined. The two optical signals were heterodyned to measure the frequency stability of the holographic filter stabilized laser, which is better than 1.65.10-8 at 30 s sample time.
