Laser Diode Selector

Rangefinder systems that are built with 1550 nm pulsed laser diodes (PLDs) also operate at high power levels yet still in the eye-safe range – due to their wavelength. Common night-vision goggles cannot detect this wavelength, which makes these PLDs particularly well suited for military laser rangefinders or friend/foe identification.

The base material of the 1550 series is InP with additional InGaAsP layers. The InGaAsP structure ensures high reliability, very good beam characteristics, and a high temperature stability. The wide operating temperature range is between –45°C and +85°C. The 1550 nm pulsed laser diodes are housed in a TO-18 can. They are also available in 9 mm packages or in customer-specific designs.

 

155G Series:
The stack design of standard diodes yields an output power of about 15-20% above the market average.

Additional characteristics:

  • Efficiency: 0.35 W/A
  • Peak power: at least 45 W at a pulse length of 150 ns
  • Beam divergence: an excellent 12° x 30°
  • Output power of a single emitter: 3 W to 12 W
  • Output power of stacked emitters: 10 W and 45 W

 

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. 

The 1550UA series achieves a peak power of 7 W to 28 W as a function of the emitting area size at 100 ns and a duty cycle of 0.1%. 

 

 

HI Series:
Even as a single emitter, high intensity PLDs with an efficiency of 0.5 W/A yield a peak power of 35 W at a beam divergence of only 12° x 25°.

 

 

Pulsed Laser Diodes with integrated FAC Optics

The Divergence of the fast axis was optimized by the additional assembly of a fast axis collimation (FAC) lens that is attached directly in front of the laser diode chip. Depending on the lens used, divergences of 3.8 mrad can be achieved. The integration of both the chip and the lens in a small, hermetically sealed TO-46 housing is particularly advantageous. This design withstands acceleration rates of over 1000 g/ms without a problem, as is required for use in military technology.

This technology is also optionally available with 905 nm pulsed laser diodes. If the wavelength has to be controlled exactly, a thermoelectric cooler (TEC) can be integrated into a TO-8 housing.

General Information 

about Pulsed Laser Diodes

Pulsed laser diodes (PLDs) are available in the wavelengths 850 nm, 905 nm and 1550 nm.

All of our PLDs are developed and manufactured at our Laser Components production facility in Canada. Customer-specific requests can, therefore, easily be accommodated. 

 

Fields of Applications

Different Wavelengths - High-Quality Housing
The standard range consists of pulsed laser diodes with the following wave-lengths: 850 nm, 905 nm, or 1550 nm. We differentiate between two product lines: high-end PLDs and low-cost PLDs. Both product lines have a high-quality metal housing in  common.

Low-Cost Series
The high-volume/low-cost series con-sists of pulsed laser  diodes in a metal housing that are best suited for  consumer  products such as laser rangefinders. SMD housings are also  available. In 2018 our first 80 W PLD received automotive qualification according to AEC-Q101.

SMD PLDs
The SMD-Option allows for high laser powers from a small housing.

QuickSwitch® PLDs
The QuickSwitch® series integrates the key components of the pulsed laser drive circuit into the same com-pact TO package as the laser chip. With a pulse width of only 2.5 ns, the QuickSwitch® devices are currently the fastest hybrid pulsed laser diodes available. Output powers from 72 W are offered.

Cost-Effective, Even When Produced in Small Amounts

Close cooperation between customer and manufacturer has been our greatest success factor in manufacturing optimally customized  products. Our customers are often pleasantly surprised by how reasonable our prices are for customized products.

LASER COMPONENTS Canada develops pulsed laser diodes (PLDs)  suited to your field of application. Almost all product parameters can be adjusted e.g., wavelength, output power, and housing. It is also possible to develop completely new products. 

Uncompromising Quality
Quality is an absolute imperative. The consistent application of  quality  management methods has resulted in the continuous advancement of  products. New products and increasing efficiency are in constant demand.

As part of quality control, a life test rack was developed to simulate very different applications. The pulsed laser diodes being tested on the life rack are pushed beyond their approved limitations.
