Specifications:
The LD-808-BA-3.5W is a high power diode laser with a typical output power of 3.5W at a central wavelength of 808nm. It features proprietary mirror coating technology for high reliability and uses Au/Sn bonding for chip attachment to a C-mount open heatsink. The device is RoHS compliant and can be packaged in a TO-can for QCW operation.

Test Conditions:
The laser operates at a heatsink temperature of 25°C. Key parameters include a threshold current of 0.6-0.7 A, an operating current of 3.5-3.8 A, and a forward voltage of 1.8-2.0 V. The divergence parallel to the p-n junction is 4-11 degrees, and perpendicular divergence is 29-34 degrees.

Absolute Maximum Ratings:
The maximum reverse voltage is 2V, and the maximum CW forward current is 4.0 A. The lead soldering temperature should not exceed 250°C for more than 5 seconds. The operating temperature range is above the dew point up to 60°C, and the storage temperature range is -40 to 85°C.

Safety and Operating Instructions:
The laser emits invisible light that is harmful to the human eye. Proper laser safety eyewear is required during operation. The device should not be operated beyond its maximum ratings to avoid damage or safety hazards. A proper heatsink is necessary for thermal management. The device should be used in a cleanroom atmosphere or dust-protected housing to prevent contamination. Electrostatic discharge (ESD) protection is crucial to prevent product failure.
