Aug. 1, 2012 - PRLog -- ORLANDO, Fla.,  – Pangolin Laser Systems, the world’s largest producer of laser display software and control hardware, announced the expansion of its LASORB product line with a series of components designed to protect high voltage lasers, such as Quantum Cascade Lasers and laser diode series strings, from damage by direct and indirect electrostatic discharge, including single, multiple, and repeated ESD events of positive or negative polarity.  LASORB, a class of component invented by Pangolin, is described as an “ESD absorber” created specifically to protect laser diodes, superluminescent diodes, and LEDs.  

“We continue to expand the LASORB line to meet specialized market needs,” said William Benner, president and chief technology officer of Pangolin.

“Until recently, literally nothing existed to protect Quantum Cascade Lasers from ESD and power surges,” said Benner.  “Quantum Cascade Lasers are a relative newcomer, with applications in medicine, environmental gas sensing and homeland security, and their popularity has grown significantly over the last five years. Since the operating voltage of these lasers is much higher than typical laser diodes, we developed a special LASORB part tailored to their needs. This new ‘2000-series part may also be used with series-connected strings of laser diodes.”

Pangolin first introduced LASORB three years ago and has continued to expand the product series to accommodate a broader range of laser products.  According the Benner, the product has proven its effectiveness and value in a variety of research and commercial applications, including those using red, infrared, blue and BLU-ray diodes.  

“Prior to LASORB, electrostatic discharge was a persistent, unsolved problem for laser diodes, especially BLU-ray and low-power single-mode red laser diodes,” he said.  “Without LASORB, a single modest ESD event can cause permanent damage, resulting in partial or complete diode failure well ahead of the manufacturers’ rated life expectancy for the diode.”

Benner said LASORB also protects against reverse bias conditions.  While Schottky diodes are typically used for this purpose, Benner said using LASORB in their place offered protection against both ESD and reverse biasing.

In addition to the newly announced series for Quantum Cascade Lasers, Pangolin produces four other series of LASORB, one optimized for low power red and infrared diodes, one for moderate power red diodes, one for 445nm blue laser diodes and a fourth optimized for 405nm BLU-ray diodes. The component package is compact and mounts in a 2-pin, through-hole configuration; Pangolin can also deliver custom packages to meet the needs of those with tight spaces.

“LASORB is a game-changer with respect protecting lasers from ESD,” stated Benner.  “There is nothing in the world like it.  Previous so-called solutions for ESD all fail in some respect: they are either too slow to respond, ineffective in the required voltage range, or incapable of absorbing the energy of a voltage surge.”  

Benner said LASORB customers currently include government, universities, and commercial companies in several countries and that it is being applied in fields of electronics, medicine, security, construction, entertainment, and scientific research.

Web Videos Demonstrate Component’s Performance

Pangolin has set up a specific website for LASORB ( offering detailed product information and datasheets, background on laser diodes and ESD, a review of the limitations of previous ESD solutions in laser diodes applications, and links to other resources.  The company has produced videos demonstrating the effects of ESD on laser diodes, including Blu-ray diodes, and the effectiveness of LASORB in protecting them.  The videos can be seen on the LASORB website ( or on YouTube: ( and
