With the rise of clean energy and the enhancement of environmental awareness, thin film solar cells are gradually replacing traditional silicon-based solar cells as an efficient energy conversion device.However, to achieve efficient solar cell conversion rates, the key is to ensure that thin film solar cells have clear edges and maximize light absorption. In this regard, the unique advantages of h...

According to a report in Nature on June 26th, a team from Stanford University in the United States has developed a titanium sapphire laser on a chip. Whether in terms of scale efficiency or cost, this achievement is a huge progress. Image source: Nature websiteTitanium sapphire lasers are indispensable in many fields such as cutting-edge quantum optics, spectroscopy, and neuroscience, but they ...

From detecting COVID in respiration to monitoring greenhouse gas concentrations, laser technology called frequency combs can recognize specific molecules as simple as carbon dioxide to as complex as monoclonal antibodies, with unparalleled accuracy and sensitivity. Although frequency combs have incredible capabilities, their ability to capture high-speed processes such as hypersonic propulsion or ...
