Lasers with well-controlled relative frequencies are indispensable for many applications in science and technology. We present a frequency-offset locking method lasers based on beat-frequency discrimination utilizing hybrid electronic $LC$ filters. The is specifically designed decoupling the tightness of lock from broadness its capture range. presented demonstration locks two free-running diode...

The objective of this article is to describe the design a new family wideband filters in rectangular waveguide based on hybrid couplings and staircase configuration. use E-plane T-junctions folded structures also discussed, order enhance out-of-band response selectivity filter with respect current state art. several prototypes discussed detail, including manufacturing sensitivity high-power ana...
