Note1: The maximum rating means the limitation over which the laser should not be operated even instant time.
This does not mean the guarantee of its lifetime. Additionally, LD lifetime is strongly dependent on the case
temperature. As for the reliability, please refer to the reliability report issued by Quality Assurance Section, HF &
Optical Semiconductor Division, Mitsubishi Electric Corporation.
