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. 2400 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.
Convenient package options such as open heatsink and window packages allow
easy integration into user systems.

where T
0
is a device constant of ~160 °K.
d. Temperature coefficient of operating current is approximately 1% per °C.
4. Modulation bandwidth of CW diode lasers is approximately 1 GHz for A package diodes.
Package diodes roll off at slightly lower frequencies due to inductance of pins and internal leads.
5. Forward voltage is typically: V
