Home / Laser diodes can withstand high temperatures
As the temperature of the laser diode rises, its maximum output power and power dissipation decreases and its operating range is reduced. Even within the absolute maximum ratings, the life becomes shorter by using at high temperatures. The effect of temperature o the performance of uncooled semiconductor LD was experimentally studied. Semiconductor lasers generate a small amount of heat during operation, so their performance varies at different temperatures.
