269-Type 1480 nm Pump Laser Module

Mounting and Connections

User Information

Table 4. Pin Information

CAUTION: This device is susceptible to damage as

a result of electrostatic discharge.

Number

Proper precautions should be taken

during both handling and testing.

Connection

TE Cooler (+)*

Thermistor

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.

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.

* A positive input into this pin cools the laser.

Fiber Characteristics

■ Length of fiber pigtail:

— 1.75 m ± 0.25 m

■ Standard fiber:

2. Mount four #2-56 screws with Fillister heads

(M2-3 mm) at the 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.

— Cladding OD: 125 µm ± 2 µm

— Acrylate buffer OD: 250 µm ± 15 µm

— Cut off wavelength: <1320 nm

■ Polarization-maintaining fiber:

— PANDA

— Cut off wavelength: <1400 nm

— Acrylate buffer: 400 µm
