SYSTEM AND METHOD FOR CONTROLLING OPTICAL OUTPUT OF A FREQUENCY CONVERSION DEVICE |
摘要 |
A system and method for improving conversion efficiency of a difference frequency generator (DFG) and/or for outputting a desired shape of the output signal, where the method includes providing a pump source, modifying the pump pulse temporal shape for optimal DFG conversion efficiency, and providing the modified pump pulse to the DFG. The pump source may be, for example, a MOPA laser or a diode or any other suitable source. In one embodiment, the pump pulse shape is modified such that an initial gain within the DFG is high, followed by a lower level signal for efficient conversion within the DFG. An example of such a shape is a double square pulse. Other configurations are possible as well such as a single rectangular pulse shape. |
