Pulsed Laser Diodes

Description

LASER COMPONENTS Canada produces high power pulsed laser diodes (PLDs) at 905 nm. The AlGaAs structure of the 905 series allows for high reliability and temperature stability; it also achieves the best beam characteristics. These 905 nm PLDs are available in a TO-18, 5.6 mm, 9 mm, or 8-32 Coax housing as well as a chip on a ceramic submount. Customer-specific designs and other wavelengths are available upon request.

These laser diodes are used in range finding, speed monitoring, laser radars, security scanners, and laser light curtains or in testing and measurement systems.

 

905D Series:

The 905D series pulsed laser diodes are available as single elements or stacks. At an efficiency of 1 W/A, the single elements achieve a peak power of 34 W, whereas the stack designs achieve an output of up to 130 W at a pulse length of 150 ns and a duty cycle of 0.1%.

 

Multi-junction Pulsed Laser Diodes:

Multi-junction pulsed laser diodes are similar to nanostack technology. LASER COMPONENTS' PLDs exhibit a peak power of up to 70 W at a pulse length of 150 ns from a single chip and are thus quite impressive.

The 70 W diode is based on three epitactically integrated emitters with an active area of altogether only 235 x 10 µm. Other versions deliver an output power of 25 W from an active area of 85 x 10 µm and 50 W from 160 x 10 µm. The small area allows the laser power to be coupled easily into a fiber and combined with microoptics.

A hermetically sealed TO housing ensures high reliability, an excellent overdrive capability, and a very precise chip alignment inside the TO can.

 

Stacked Multi-Junction Pulsed Laser Diodes (PLDs):

Stacked multi-junction pulsed laser diodes deliver a peak power of over 210 W at 905 nm. They are based on several epitactically integrated emitters with a total emitting area of 200 µm x 10 µm and thus deliver an optimal power intensity:

Characteristics of single emitters

  • Pulse length: 100 ns
  • Peak power: at least 75 W

Characteristics of stacked versions:

  • Pulse length: 100 ns
  • Peak power: over 140 W or 210 W

Application fields include: ceilometers, altimeters, LIDAR, distance measurements

 

UA Series - An Inexpensive Alternative to PLDs in a Plastic Housing

UA series pulsed laser diodes are high quality diodes hermetically sealed in a TO-56 metal housing. Produced in large quantities, they can compete in price with PLDs in a plastic housing. In addition, they are highly reliable, possess excellent overdrive capabilities, and feature optimal thermal stability and a very precise chip alignment inside the housing.

As a single element design, the 905DxxUA series achieves a peak power of 6 W to 19 W. The multi-junction versions deliver a peak power of 25 W, 50 W, and 75 W at 150 ns and a duty cycle of 0.1%.


QS Series - Driver integrated 905nm PLDs


Ultra compact module containing a high current switch, charge storage capacitor and PLD inside a small pkg.

TO-56 with 5pins, 2.5ns FWHM pulse width available. 200kHz and evalulation board available.
