COMMERCIAL LASERS High-Power 10 W 9xx nm Fiber-Coupled Diode Laser with Feedback Protection 6398-L4i Series Key Features • Full fiber laser feedback protection • 10 W output power • High reliability • 105 µm aperture • 0.22 or 0.15 N A • Isolated electrical contacts Application • Fiber laser pumping The JDSU L4i Series fiber-coupled diode laser is the latest solution in our L4 platform for the fiber laser pumping market. The L4i design, which leverages the L4 footprint, offers a high degree of feedback protection from any fiber laser wavelength. This feature allows end users to operate the fiber laser in an environment virtually free from the risk of feedback to the diode laser, resulting in a less costly solution than a traditional isolation system. Our 6398-L4i series diode lasers offer 10 W of power from a 105 µm fiber. In addition, the L4i multimode pump modules take advantage of the existing global JDSU manufacturing infrastructure to offer both high brightness and a small footprint, with consistent high reliability in a cost-effective solution.

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.
