Quantum Cascade Lasers

High Peak Power Source



Alpes Lasers introduces its new high peak power sources. Based on a unique gain-guided design, these Quantum Cascade Lasers are optimized for emitting short pulses from 20 ns to 1000 ns with minimum peak power of 20 W, or ~5 microjoules per pulse. Available on submount or in a HHL package with a dedicated driver, these lasers can be used for free-space optical communications, LIDAR applications and IR countermeasures.


You can read more about the technology behind these high peak power devices in this  Optics Express paper.

WaterSpy

Alpes Lasers collaborates in the WaterSpy partnership which aims at  developing water quality analysis photonics technology suitable for inline, field measurements. WaterSpy technology will be integrated, for validation purposes, to a commercially successful water quality monitoring platform, in the form of a portable device add-on. The project is funded by Horizon 2020, the EU Framework Programme for Research and Innovation for 2014-2020.

External Cavity 

Alpes Lasers introduces a new External Cavity Laser Kit (ECLK)  designed for single-mode operation with wide spectral tunability. The ECLK consists of a quantum cascade laser (QCL) gain chip, a grating-tuned extended optical cavity in Littrow configuration, laser drive electronics, an Alpes Lasers TC-3 temperature controller, and a graphical user interface software.

QCL for breath analysis


In this paper published recently in the Photonics journal, quantum cascade lasers from Alpes Lasers are used in a new method to measure liver function in patients by analyzing their breath in real time, allowing a reduction of mortality rates by more than 70% in laser resections.
