Underwater optical communication faces a natural barrier known as the \u201cgreen gap\u201d. Traditional lasers cannot form stable transmission in seawater, limiting the development of underwater detection and submarine robot data transmission. The newly developed chip-scale yellow laser <\/a>effectively solves the green gap problem and improves underwater communication stability.<\/p>\n\n\n\n

\"\"<\/a><\/figure>\n\n\n\n

Seawater absorbs most blue and red light waves. Only specific yellow-green band light can transmit farther in shallow seawater. Traditional semiconductor lasers lack stable yellow-band output, causing weak signal and short transmission distance.<\/p>\n\n\n\n

Chip-scale yellow laser modules realize high-purity, stable yellow wavelength output. The light beam matches the seawater transmission window perfectly, greatly increasing underwater optical signal penetration distance and anti-attenuation capability.<\/p>\n\n\n\n

Small size, low power consumption, and high stability make chip-scale yellow lasers easy to integrate into underwater sensors, ROVs, and marine monitoring devices.<\/p>\n\n\n\n

This new laser technology significantly enhances the reliability of shallow sea optical communication, providing new technical support for marine exploration, underwater monitoring, and offshore engineering data transmission.<\/p>\n\n\n\n
