Wavelength of laser diode in CD player
The laser diode used in CD players typically operates at a wavelength of 780 nm, which is in the infrared range of the electromagnetic spectrum. This wavelength was chosen because it is easily absorbed by the aluminum or gold reflective layer on the CD, allowing for accurate reading. The first CD players used a laser diode with a wavelength of 780 nanometers (nm) to read the data stored on the disc. This early technology was pioneered by companies like Philips and Sony, who worked together to develop the CD format. This wavelength is chosen because it is long enough to penetrate the plastic substrate of the CD, but short enough to be focused onto the tiny pits and lands on the CD. The visible light spectrum past 720nm.

New Swedish Power Storage Solution
Since 2023, Ingrid Capacity has partnered with BW ESS to develop 14 large-scale battery storage projects at strategically selected locations throughout Sweden's electricity grid, situated in the electricity price areas SE3 and SE4. Developer and optimiser Ingrid Capacity and energy storage owner-operator BW ESS have been. The electricity network company Ellevio is diversifying its business to help industry and companies become fossil-free through electrification. The first investment is Sweden's largest Battery Energy Storge Solution (BESS) that enables more renewable energy in the electricity system and a better. Battery Energy Storage Systems (BESS) are becoming essential to Sweden's transition toward a fossil-free energy system. While the country leads in renewable adoption—reaching 98% fossil-free electricity in 2023—intermittency from wind and solar continues to cause major grid instability and price. As Sweden's energy system races through one of the fastest storage build-outs in Europe, it's the perfect moment to take stock of who's actually leading the charge.
