Quantum Cooling Systems using Mode Controlled Blue Lasers (CoolBlue2)

点击翻译按钮获取中文摘要

'CoolBlue is a highly innovative project with a goal to develop next generation GaN laser technology for implementation in quantum sensors based on atomic cooling. Conventional laser sources for these applications are complex and inefficient whereas a direct blue laser diode source could offer many advantages such as increased power, lower complexity, and smaller size, potentially transforming quantum sensors such as frequency standards from laboratory instruments into miniaturised, robust devices. The project will consist of two cycles of laser design, fabrication and test, in which we will optimise key laser parameters including linewidth and power. The project will be led by CSTG Ltd in partnership with the University of Glasgow and Aston University.'
