“…As is seen, all samples are alive without any signs of degradation even after 10,000hours aging at 70° C, 5mW. Furthermore, for output power of 15mW, very stable operation with aging time of over 2,500hours at 50° C was obtained [1,2]. Operation current change of three Crank TJS lasers in aging test.…”
