Description

LSC3X00 laser modules are high
reliability fiber optic light sources
operating in the 1300 nanometer
band. They are particularly well
suited for applications where low
power dissipation is required.

The internal semiconductor lasers
are based upon InGaAsP buried
heterostructure (BH) technology
and fabricated by the Metal­Organic Vapor Phase Epitaxy
(MOVPE) process, resulting in
long lifetimes and modest
threshold currents.

The LSC3X00 package includes a
photodiode for monitoring the
laser output. A longhorn type
heatsink mounting flange is
incorporated in the industry
standard 14 pin DIL package.

Two basic varieties are offered
for alternative power ranges. The
“low power” LSC3300 covers the
power range between 100 µW

and 625 µW. The “high power”
LSC3100 uses the same laser
chip, but with tighter fiber
coupling to achieve output
powers from 1 mW to 2.5 mW.

The low cost outer package is
made feasible by our unique
design of hermetic miniature
laser submodule which houses
the electro-optic devices. The
submodule concept is used as a
building block in many other
Hewlett-Packard products
including cooled 1 mW 14 pin
lasers and DFB modules.

Laser Safety Warning

This device is a Class IIIb (3b) Laser Product. It may emit invisible laser radiation if operated with the fiber pigtail disconnected. To avoid
possible eye damage do not look into an unconnected fiber pigtail during laser operation. Do not exceed specified operating limits.
