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.
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 µm 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.
