CW Source Laser

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute

stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those

given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can

adversely affect device reliability.
