COMMERCIAL LASERS
Key Features • 100 µm emitter width
• High-efficiency, MOCVD quantum well design
• High reliability
The 63xx series diode lasers represent an advancement in high continuous-wave
(CW) optical power and ultrahigh brightness with unsurpassed reliability. The
small emitting aperture, combined with low beam divergence, makes the 63xx series
the highest brightness family of CW diode lasers available in the industry.
The 63xx series consists of partially coherent broad-area emitters, with relatively
uniform emission over the emitting aperture. Operation is multilongitudinal
mode, with a spectral envelope width of approximately 3.5 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 63xx series
offers up to 10 W of output from a 100 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 the lifetime and increase reliability.
These diodes are mounted on a low thermal-resistance, electrically isolated
submount, allowing for easy integration into user systems.

User Safety
Safety and Operating Considerations
The laser light emitted from this diode laser is invisible and may be harmful to the human eye. Avoid looking directly into the
diode laser, 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 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 power supplies are used, the diode
laser should be connected 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.
