Researchers at the University of St. Andrews in Scotland have manufactured the first organic semiconductor laser to operate without the need for a separate light source - which has proven to be extremely challenging. The new all electric driven laser is more compact than previous devices and operates in the visible light region of the electromagnetic spectrum. Therefore, its developers stated that...
Recently, American fiber laser giant IPG Photonics announced the launch of a new laser series specifically designed for the additive manufacturing field.The highlight of this series of lasers lies in its integration of IPG's unique dual beam technology, which can independently regulate and simultaneously emit core and ring beams, setting a new benchmark in accuracy, efficiency, and reliability.Ba...
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...
Recently, SMART Photonics, a Dutch photonic integrated circuit manufacturer, announced a major decision to transfer its entire production capacity from 3-inch wafers to 4-inch silicon substrates, thereby expanding the production scale of photonic chips and significantly reducing chip prices.According to the company, SMART Photonics is one of the first photonic integrated circuit foundries to provi...
Holographic display technology provides the ultimate solution for true 3D display, with enormous potential in augmented reality and virtual reality. However, the color and viewing angle of holographic 3D displays mainly depend on the wavelength of the laser and the pixel size of the current spatial light modulator. The inevitable color difference and narrow viewing angle in conventional systems se...
