Imaging microscopic biological specimens demands greater resolution than can typically be attained via conventional microscopy. Consider a cell, which is predominantly composed of water and is subsequently transparent. Visible light-based microscopy will fail to provide much detail about cellular structures, as most light on the range of 400–700 nanometers (nm) will simply transmit through. This … Continue reading
The high absorption of infrared light in silica is an established trait that has seen longwave infrared lasers operating at 10.6 µm and 9.3 µm, implemented for a variety of applications over the years. In this article, we will look at three such use cases: laser damage growth mitigation, manufacturing of freeform micro-optics, and fiber … Continue reading
In a video Dr. Yong Zhang, CEO of Access Laser, explains the different modes of cooling available for their longwave infrared lasers and the advantages of each method. To watch this video, click here. Access Laser manufactures longwave (9.0 to 11.4 µm) and midwave (5.2 to 5.8 µm) infrared lasers for R&D, advanced manufacturing, and … Continue reading
A recent article in “Nature,” entitled “Cytoskeletal disorganization underlies PABPN1-mediated myogenic disability” suggests that “poor cytoskeletal mechanical features are caused by altered expression levels of cytoskeletal proteins and contribute to muscle wasting and atrophy.” This research involved Brillouin light scattering microscopy using a home-built Brillouin confocal microscope. A single mode torus 532 nm laser from … Continue reading
Laser technology as we know it was first envisaged on a park bench in Washington in 1951, when Charles Townes thought up the concept of Microwave Amplification by Stimulated Emission of Radiation (MASER). Within ten years, this idea had germinated, yielding the first solid-state laser with a ruby gain medium. Sixty years of near non-stop … Continue reading
Dr. Yong Zhang, founder and CTO of Access Laser, presents a short video about laser stability. He explains the relationship between laser temperature and stability of the power, frequency and wavelength. The video focuses on the features of CO2 lasers. To watch the video, click here. To request more information or a quotation for Access … Continue reading
