The SDL-2400 series laser diodes 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 SDL-2400 series the highest-brightness
family of CW laser diodes available in the
industry today.
The SDL-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. SDL-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.

User Safety
Safety and Operating Considerations
The laser light emitted from this laser diode is invisible
and may be harmful to the human eye. Avoid looking
directly into the laser diode, 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 laser diode 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 laser diodes may be damaged by excessive drive
current or switching transients. When power supplies are
used, the laser diode should be connected with the main
power on and the output voltage at zero. The current
should be increased slowly while the laser diode 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 laser diode 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 laser diode failure. Take
extreme precaution to prevent ESD. Use wrist straps,
grounded work surfaces and rigorous antistatic
techniques when handling laser diodes.
21 CFR 1040.10 Compliance
Because of the small size of these devices, each of the
labels shown is attached to the individual shipping
container. They are illustrated here to comply with
21 CFR 1040.10 as applicable under the Radiation
Control for Health and Safety Act of 1968.
