Shanghai scientists develop ultranarrow bandwidth mode-locked laser with a widely-tunable pulse duration. Shanghai’s ultranarrow bandwidth mode-locked laser. Click for info. Ultranarrow bandwidth mode ...

The ultranarrow bandwidth mode-locked laser can be tuned for pulse duration. It uses a new filter configuration and single-walled carbon nanotube as saturable absorbers. The laser has a nearly ...

Using a spectrum analyzer for pulsed measurements has always required a careful understanding and knowledge of the parameters of the pulse signal, as well as the subsequent operation of the spectrum ...

As engineers, you use many components and devicesevery day that you treat as black boxes. You are concernedonly about the inputs and outputs of the blackbox, and that approach is acceptable provided ...
