COMMERCIAL LASERS Diode Lasers, 0.5 to 4.0 W, 8xx nm 2300 Series Key Features * 0.5, 1.2, 2.0 and 4.0 W CW power * 50, 100, 200 and 500 m apertures * High-efficiency MOCVD quantum well design * Open heatsink package * High reliability Applications * Solid-state laser pumping * Medical/ophthalmic applications * Free-space communication * Beacons/illumination The 2300 series diode lasers offer high continuous wave (CW) optical power and high brightness with unsurpassed reliability. The small emitting aperture, combined with low beam divergence, makes the 2300 series one of the highestbrightness CW diode lasers available in the industry today. The 2300 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 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. Emitting apertures for 2300 variants range from 50 to 500 m, giving CW power output capability of up to 4 W with superlative reliability. For higher-power 100 and 200 m aperture devices, JDSU's 2400 Series diode lasers are ideal. 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 come mounted on conventional open heatsink packages that allow easy integration into user systems.

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 using power supplies, connect the diode laser 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 50 C rather than 30 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.
