| COMMERCIAL LASERS High-Power 2 W 830 nm Fiber-Coupled Diode Laser 2486-L4 Series Key Features * 2 W output power * High reliability * 60 m aperture * 0.22 NA * Isolated electrical contacts Applications * Computer-to-plate printing * Flexographic printing * Illumination The new high-brightness 2486-L4 series laser diodes offer up to 2 W from a 60-m fiber into 0.22 numerical aperture (NA)--ideal for thermal printing and other applications that require high brightness and a long life. The dramatic increase in output power, from the 60-micron fiber, also enables new technologies, such as flexography, illumination, and several material processing applications. The 2486-L4 series is available with customer-selectable fiber length and fiber termination, including bare fiber, SMA, and ST connectors.

Sample: L4-2486-003 User Safety Safety and Operating Considerations The laser light emitted from this diode laser is invisible and may be harmful to the human eye. Avoid looking directly into the diode laser or into the collimated beam along its optical axis when the device is in operation. CAUTION: THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT WILL INCREASE EYE HAZARD. Operating the diode laser outside of its maximum ratings may cause device failure or a safety hazard. Power supplies used with the component must be employed such that the maximum peak optical power cannot be exceeded. CW diode lasers may be damaged by excessive drive current or switching transients. When power supplies are used, the diode laser should be connected with the main power on and the output voltage at zero. The current should be increased slowly while the diode laser output power and the drive current are monitored. Device degradation accelerates with increased temperature, and therefore careful attention to minimizing the case temperature is advised. For example, life expectancy will decrease by a factor of four if the case is operated at 50 C rather than 25 C. A proper heatsink for the diode laser on a thermal radiator will greatly enhance laser life. Firmly mount the laser on a radiator with a thermal impedance of less than 0.5 C/W for increased reliability. ESD PROTECTION--Electrostatic discharge is the primary cause of unexpected diode laser failure. Take extreme precaution to prevent ESD. Use wrist straps, grounded work surfaces, and rigorous antistatic techniques when handling diode lasers. Labeling 21 CFR 1040.10 Compliance Because of the small size of these devices, each of the labels shown is attached to the individual shipping container. They are illustrated here to comply with 21 CFR 1040.10 as applicable under the Radiation Control for Health and Safety Act of 1968.
