source:eeNewsResearchers in Germany are developing directly tunable laser sources from 532 nm to 561 nm to 590 nm with up to 2W output power in continuous wave operation.The compact laser sources being developed by the Ferdinand-Braun-Institut, Leibniz-Institut für H?chstfrequenztechnik (FBH) have the potential to replace significantly larger dye and copper bromide lasers.The researchers increased the peak output power of its diode laser bars in quasi-continuous operation by up to four times while maintaining excellent efficiency. This reduces the cost in euros per watt – a key parameter ...

source:Science NewsIsraeli and German researchers have developed a way to force an array of vertical cavity lasers to act together as a single laser -- a highly effective laser network the size of a grain of sand. The findings are presented in a new joint research paper published online by the journal Science on Friday, September 24.Cell phones, car sensors or data transmission in fiber optic networks are all using so called Vertical-Cavity Surface-Emitting Lasers (VCSELs) -- semiconductor lasers that are firmly anchored in our everyday technology. Though widely used, the VCSEL device has mini...

source:NatureAn array of 30 lasers that acts as a single light source represents a key step towards the development of large-scale, high-powered lasers on a microchip1.Microchip lasers are tiny devices found in items ranging from computer mice to mobile phones. The power emitted by a single such laser is low. Arrays of lasers are typically more powerful than individual ones, but it has been difficult to produce an array of chip-based lasers that emit light waves that oscillate in step. Such synchronized, or ‘coherent’, light is a key property of a laser beam.Mordechai Segev at the Technion–Isr...
