LOTMAXX has announced the launch of the ET model, a new type of 3D printer that can also be used as a laser cutting machine. According to the manufacturer, the core component is a fast direct extruder with a printing speed of up to 500 millimeters per second.LOTMAXX ET features an all metal casing with a printing volume of 250 x 250 x 265 mm. According to the announcement, as a special feature, th...
With the explosive growth of data traffic, the market is extremely eager for hybrid photonic integrated circuits that can combine various optical components on a single chip.Silicon is an excellent material for photonic integrated circuits (PICs), but achieving high-performance laser sources in silicon still poses challenges. The monolithic integration of III-V quantum dot (QD) lasers on silicon i...
We investigated the potential of laser selection in a wide optical range from ultraviolet to visible light, and then to infrared (excitation wavelengths of 325, 532, 785, and 1064 nm), in order to combine and analyze extreme microorganisms related to Earth (such as Cryptomeria elegans, cold floating nematodes, and circular green algae), carbon water compound molecules, as well as simulated mineral...
