Laser-based LiDAR sensors can provide highly accurate scans of three-dimensional spaces, and as such are crucial in applications ranging from autonomous vehicles to geological mapping technologies and emergency response systems. High-quality lasers are also a key part of the high-speed, high-volume data centers that are the backbone of the internet.<\/p>\n<p>When assessing the quality of a <a href=\"https:\/\/phys.org\/tags\/laser\/\" rel=\"tag\" class=\"\">laser<\/a>, researchers look to the noise in a laser\u2019s frequency, or the number of times the laser\u2019s light wave toggles in each second. Low-quality, \u201cnoisy\u201d lasers have more random variations in those toggles, making them useless for systems that are meant to return <a href=\"https:\/\/phys.org\/tags\/accurate+measurements\/\" rel=\"tag\" class=\"\">accurate measurements<\/a> or convey densely packed information.<\/p>\n<p>At present, lasers with adequately low frequency noise are bulky, expensive and an impractical choice for mass manufacturing. Penn Engineers have set out to solve this problem with a device called a \u201cphase noise filter\u201d that can turn low-cost, compact lasers into those suitable for LiDAR and more.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Many emerging technologies rely on high-quality lasers.
