Scientists at Purdue University in the United States have developed a new type of two-photon polymerization technology. This technology cleverly combines two lasers and utilizes 3D printing technology to print complex high-resolution 3D structures while reducing femtosecond laser power by 50%. It helps to reduce the cost of high-resolution 3D printing technology, thereby further expanding its appl...
In a study published in Optics Express, the research team led by Professor Fu Yuxi of the Xi'an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences developed the room temperature holmium doped lithium yttrium fluoride (Ho: YLF) composite thin slice laser for the first time, which can achieve high efficiency and high-quality CW laser output.Laser devices operating...
As a promising imaging modality that combines the high spatial resolution of optical imaging and the deep tissue penetration ability of ultrasound imaging, photoacoustic microscopy (PAM) has attracted a lot of attention in the field of biomedical research, and has a wide range of applications in many fields, such as tumor detection, dermatology, and vascular morphology assessment. Depending on the...
OLED is located at the top and is formed by an organic layer between the contacts. Apply voltage to it, inject charge and generate light, which in turn excites organic laser. Organic lasers contain a grating that can generate feedback and diffract some of the laser out of the structure.Organic laserResearchers have created the first organic semiconductor laser to operate without the need for a sep...
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 ...
