The GFP is used as the laser’s “gain medium”, where light amplification takes place. The cells were then placed between two tiny mirrors, just 20 millionths of a meter across, which acted as the “laser cavity” in which light could bounce many times through the cell. Upon bathing the cell with blue light, it could be seen to emit directed and intense green laser light. Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. Gould’s notes included possible applications for a laser, such as spectrometry, interferometry, radar, and nuclear fusion.
That question prompts competing claims from suppliers—but very little concrete data. When one vendor performed controlled tests to get some answers, its results, published here for the first time, prompted further debate about the difficulties of making valid comparisons and the many complex issues involved in dryer selection. RDE+ is a rapid, robust, integrated process and toolchain to deliver design, development, validation and verification with optimum efficiency.
The project revolves around automated, flexible laser processing designed to disassemble electronic devices to selectively extract valuable component parts at the end of their useful life. The laser cladding process resulted in 80% cost savings for a sawmill. An ultrashort-pulse laser can remove graphite-based anode material from 10-µm-thick copper foil at a rate of up to 1760 mm3/min without damaging it. Simple operation, power can be hand-held or with the robot to achieve automated cleaning. Without any chemical cleaning fluid, no supplies, safety and environmental protection.
The cavity converts the low-quality diode light into single-mode laser light. One of the fiber Bragg gratings acts as a total reflector, while the other serves as a partial reflector or output coupler. The solid-state architecture of fiber lasers makes them insusceptible to environmental factors such as dust, moisture, and free-space air perturbations.
