The HI-Series 1550nm Pulsed Laser Diodes; a Dependable Choice

The HI-Series, since its release in 2008, has proved to be both reliable, and technically a very good choice in applications where a narrow beam divergence (in both axis) and high slope efficiency (0.38W/A) presents a key advantage. Both the already-narrow divergence of 25 by 12 degrees FWHM and the fact that the device has a smaller emitting area compared to many other 1550nm pulsed laser diodes on the market, allow the light to reach high intensities at the chosen target. The HI155G1S14S and HI155G1S14SCB are two of the most popular models in the series.

The good news we have today is that we are now more price competitive; customers are choosing to use our HI-Series lasers and using them in their OEM systems, allowing us to pass on the economies-of-scale savings. Furthermore, if you later require further collimation a pin-for-pin and EMC compatible upgrade to the same laser is available, in production, with an integrated fast-axis collimating lens that yields 5mrads by 12 degrees letting you easily adapt your systems to those more challenging requirements.
