We report a novel high-power bistable distributed feedback (DFB) semiconductor laser diode operating near 1060 nm. which is realized by inserting a high-bandgap electron barrier layer and a grating layer in a super large optical cavity laser design. Optical and electrical bistable characteristics are both observed for this device. An on-state optical output power of 98 mW and an on-of... https://chefesquipmenters.shop/product-category/scissors/
