Juguang Technology launches miniaturized high-power semiconductor laser stack GS09 and GA03

Dark solitons - the extinction region in a bright background - spontaneously form in a ring semiconductor laser. Observations conducted by an international research group may lead to improvements in molecular spectroscopy and integrated optoelectronics.Frequency comb - a pulse laser that outputs light at equidistant frequencies - is one of the most important achievements in the history of laser ph...

The new device is a frequency comb - a special type of laser that can generate multiple wavelengths of light, each with a fixed frequency interval. On the spectrogram, it looks a bit like the teeth of a comb. In approximately a quarter century since their first development, these "cursor rulers" have completely transformed various high-precision measurements from timing to molecular detection. In ...
