30 Σεπ 2022 · A near-infrared 980-nm laser impacts upon water by passing through a 250-μm-thick sapphire glass, which is optically transparent at 185–5000 nm (Fig. 1a).
4 ημέρες πριν · Ultrabright broadband near-infrared (NIR) phosphor-converted laser diode (pc-LD) as a light source is increasingly essential for improving the sensitivity and spatial resolution of intelligent NIR spectroscopy technologies. However, the performance of NIR pc-LD is greatly hindered by the low external quantum efficiency (EQE) and poor thermal ...
In particular, low energy near-infrared (NIR, 700–1700 nm) light possesses lower phototoxicity and higher tissue penetration depth in living systems as compared with ultraviolet/visible light, making it a promising tool for in vivo applications.
