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 ...
Recently, SuperLight Photonics, a leading laser technology manufacturer, announced that it has received strategic investment from global venture capital firm Hamamatsu Ventures, which will be used to promote long-term innovation and collaborative development of its laser technology.
