Important Notices

Laser Safety

This device emits invisible laser radiation that can be hazardous to the human eye. Avoid direct exposure to the fiber output or to the collimated beam along its optical axis while the device is in operation. Appropriate laser safety eyewear must be worn during operation.

Absolute Maximum Ratings

Absolute maximum ratings may be applied to the device only for short periods. Extended exposure to maximum ratings, or exposure to one or more values above the maximum ratings, may result in device damage or affect device reliability.

Operating Conditions

Operation of the product outside the maximum ratings may cause device failure or safety hazards. The power supply used with the device must be limited so that the maximum peak optical power cannot be exceeded. The device requires a suitable heatsink on the mounting surface; adequate heat dissipation and thermal conductivity must be ensured. This device is an open‑heatsink laser diode; it may only be operated in a cleanroom environment or in a dust‑proof housing. Operating temperature and relative humidity must be controlled to avoid condensation on the laser facet. Any contamination of or contact with the laser facet must be avoided.

ESD Protection

Electrostatic discharge is a major cause of unexpected product failure. Take extreme precautions to prevent ESD. Use wrist straps, grounded work surfaces, and strict anti‑static techniques when handling the product.
