COMMERCIAL LASERS Diode Lasers, High Brightness 0.6 to 8.5 W, 8xx nm 24xx Series Key Features * 35 - 200 m aperatures available * High-efficiency, MOCVD quantum well design * Open heat sink packages and encapsulated devices * High reliability The 24xx series diode lasers represent a breakthrough in high continuous wave (CW) optical power and ultra high brightness with unsurpassed reliability. The small emitting aperture, combined with low beam divergence, makes the 24xx series the highest brightness family of CW diode lasers available in the industry. Applications * Solid-state laser pumping * Medical/ophthalmic applications * Free-space communication * Beacons/illumination The 24xx series consists of partially coherent broad-area emitters, with relatively uniform emission over the emitting aperture. Operation is multi-longitudinal mode with a spectral envelope width of approximately 2 nm full width half maximum (FWHM). The far field beam divergence in the plane perpendicular to the P/N junction is nearly Gaussian, while the lateral beam profile exhibits a multiple-transverse mode pattern typical of broad-area emitters. The 24xx series offer up to 8.5 W of output from a 200 m aperture. The high efficiency of the quantum well structure, combined with low thermal resistance epi-down chip mounting, provides minimum junction temperature at high optical power. Low junction temperature and low thermal resistance packages extend lifetime and increase reliability. These diodes are mounted on conventional open heat sink packages and encapsulated devices, allowing for easy integration into user systems. north america : 800 498-JDSU (5378) worldwide : +800 5378-JDSU website : www.jdsu.com 24XX SERIES DIODE LASERS 2 Dimensions Diagrams (Specifications in inches [mm] unless otherwise noted.)

Avoid looking directly into the diode laser, into the collimated beam along its optical axis, or directly into the fiber 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 minimize the case temperature is advised. For example, life expectancy will decrease by a factor of four if the case is operated at 50C rather than 30C. 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 0.5C/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. JDS Uniphase Corporation SAN JOSE, CALIFORNIA MODEL: Labeling 95134 U. S. A.
