By introducing “strained quantum wells,” manufacturers can modify the band structure to reduce the threshold current and increase the differential quantum efficiency. However, excessive strain leads to dislocations, which act as non-radiative recombination centers. These defects generate heat instead of light, leading to the dreaded Catastrophic Optical Damage (COD) at the laser facets.<\/p>\n\n\n\n \u062c\u0632\u0621 \u0643\u0628\u064a\u0631 \u0645\u0646 \u0633\u0639\u0631 \u0627\u0644\u0635\u0645\u0627\u0645 \u0627\u0644\u062b\u0646\u0627\u0626\u064a \u0627\u0644\u0644\u064a\u0632\u0631\u064a<\/strong> \u0625\u0644\u0649 \u0645\u0639\u0627\u0644\u062c\u0629 \u0645\u0627 \u0628\u0639\u062f \u0627\u0644\u0646\u0645\u0648\u060c \u0648\u062a\u062d\u062f\u064a\u062f\u064b\u0627 \u062a\u062e\u0645\u064a\u0644 \u0627\u0644\u0648\u062c\u0647 \u0648\u0627\u0644\u0625\u062f\u0627\u0631\u0629 \u0627\u0644\u062d\u0631\u0627\u0631\u064a\u0629. \u0648\u062c\u0647 \u0627\u0644\u0625\u062e\u0631\u0627\u062c \u0647\u0648 \u0627\u0644\u062c\u0632\u0621 \u0627\u0644\u0623\u0643\u062b\u0631 \u0636\u0639\u0641\u064b\u0627 \u0645\u0646 \u0644\u064a\u0632\u0631 \u062f\u064a\u0648\u062f<\/strong>. \u0648\u0646\u0638\u0631\u064b\u0627 \u0644\u0623\u0646 \u0643\u062b\u0627\u0641\u0629 \u0627\u0644\u0637\u0627\u0642\u0629 \u0627\u0644\u0636\u0648\u0626\u064a\u0629 \u0641\u064a \u0627\u0644\u0648\u0627\u062c\u0647\u0629 \u064a\u0645\u0643\u0646 \u0623\u0646 \u062a\u0635\u0644 \u0625\u0644\u0649 \u0639\u062f\u0629 \u0645\u064a\u062c\u0627\u0648\u0627\u062a \u0644\u0643\u0644 \u0633\u0646\u062a\u064a\u0645\u062a\u0631 \u0645\u0631\u0628\u0639\u060c \u0641\u062d\u062a\u0649 \u0627\u0644\u0627\u0645\u062a\u0635\u0627\u0635 \u0627\u0644\u0645\u062c\u0647\u0631\u064a \u064a\u0645\u0643\u0646 \u0623\u0646 \u064a\u0624\u062f\u064a \u0625\u0644\u0649 \u0630\u0648\u0628\u0627\u0646 \u0645\u0648\u0636\u0639\u064a.<\/p>\n\n\n\n
