NoticeThe laser emitted by this device is invisible and potentially hazardous to human eyes. Avoid direct viewing of fiber output or looking into the collimated beam along the optical axis during operation. Appropriate laser safety goggles must be worn at all times.

Absolute maximum ratings shall only be applied to the device for a short duration. Long-term operation at or beyond maximum ratings may cause permanent damage and degrade long-term reliability.

Operation outside the specified maximum ratings will result in device failure and potential safety hazards. A dedicated matched power supply must be used to ensure the peak optical power does not exceed the limit. The device requires a qualified heat sink with sufficient heat dissipation and thermal conductivity.

This is an open-heatsink laser diode. It shall only be operated in a cleanroom environment or dustproof enclosure. Operating temperature and relative humidity must be controlled to prevent condensation on the laser facet. Any contamination or physical contact with the laser facet must be strictly avoided.

ESD ProtectionElectrostatic discharge is a primary cause of unexpected device failure. Strict ESD precautions are mandatory. Wear an anti-static wrist strap, use grounded work surfaces, and follow standardized anti-static operating procedures during handling.
