The 2400 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 2400 series
the highest-brightness family of CW diode lasers available in the industry today.
The 2400 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. The 2400 Series variants range from 2 W
output from a 100 µm aperture to 3 W from a 200 µm aperture with superlative
reliability.
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.
