Description
The 269-type pump laser module with fiber grating
represents a family of thermoelectrically cooled,
high-power lasers. These modules utilize a fiber
Bragg grating to achieve stable wavelength perfor-
mance within the 1420 nm to 1510 nm range, over
the full operating temperature range. They are
designed as continuous-wave (CW) optical pump
sources for dense wavelength-division multiplexing
(DWDM) EDFA and Raman applications operating in
the C- and L-bands. The 269-type laser modules with
polarization-maintaining fiber are particularly suitable
for use in RPM designs requiring the high-power
combinations of multiple pumps.
The laser optical spectrum is locked by the fiber grat-
ing over a wide optical power range. The optical
spectrum is v ery narrow and the peak wavelength is
nearly insensitive to temperature v ariations and back
reflections.
The laser modules incorporate a high-power, quan-
tum-well laser chip that achieves grating-stabilized
fiber powers ranging to 280 mW.
An integral thermoelectric cooler (TEC) stabilizes the
laser at room temperature and, combined with a her-
metic environment, allows the device to achieve
high-power operation ov er the e xtended temperature
range of 0 °C to 75 °C. An internal InGaAs PIN pho-
todiode, mounted behind the laser diode, functions
as the laser detector and monitors light emissions
from the rear facet of the laser.
The 269-type module is off ered in a 14-pin, hermetic
b utterfly package.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the de vice. These are abso-
lute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess
of those given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended
periods can adversely affect device reliability.
Handling Precautions

HBM (resistance = 1.5 k, capacitance = 100 pF) is widely used and, therefore, can be used for comparison pur-
poses. The HBM ESD withstand voltage established for the 269-type laser pump module is ±500 V.

Mounting and Connections
CA UTION: This device is susceptible to damage as
a result of electrostatic discharge.
Proper precautions should be taken
during both handling and testing.
The base of the laser module (see Outline Diagram)
should be maintained at or below 75 °C (maximum)
during operation. Interfaces between the laser module
base and heat sink must be clean, and the use of a
thermal filler may be necessary.
Mounting Instructions
The minimum fiber bend radius is 1.0 in.
To avoid degradation in performance, mount the mod-
ule on the board as follows:
1. Place the bottom flange of the module on a flat heat
sink at least 0.5 in. x 1.180 in. (12.7 mm x 30 mm)
in size. The surface finish of the heat sink should be
better than 32 µin. (0.8 µm), and the surface flat-
ness must be better than 0.001 in. (25.4 µm). Using
thermal conductive grease is optional; however,
thermal performance may be improved if conductive
grease is applied between the bottom flange and
the heat sink.
2. Mount four #2-56 screws with Fillister heads
(M2-3 mm) at t he four screw hole locations (see
Outline Diagram). The Fillister head diameter must
not exceed 0.140 in. (3.55 mm). Do not apply more
than 1 in./lb. of torque to the screws.
