Quantum Cascade Lasers (QCL) emitting from 4 to 17 micro-meters Mar 11, 2009

This range is available within two weeks. If a specific laser is not available, it can be manufactured to order. The exhibited powers ranges between 1 and 100 mW. The line-width for pulsed devices is in the order of 300 MHz, which is compatible with atmospheric pressure broadened lines. The line-width can attain values as low as a few MHz for CW devices which facilitates low pressure gas lines absorption measurement. The narrowest observed line of a stabilised QCL was less then 6 Hz wide.

Various packages are available, from extra-small footprint TO-8 for extremely low duty cycle operation to medium footprint TO-3 for all type of pulsed operation including DC-bias electrical frequency tuning or high duty cycle pulsed operation and to High Heat Load (HHL) packages for CW operation.

Space flight qualified version of the HHL package is available.

An evaluation starter kit can also be purchased from Alpes Lasers. It comprises all the necessary accessories and drive electronics to operate either the continuous wave, the pulsed or TeraHertz devices. It offers the experimentalists a plug and play approach to obtain mid infrared coherent radiation of their choice.

Alpes Lasers is proud to make available a line of TeraHertz lasers with central emission wavelength between 65 and 250 micro-meters and operating at the temperature of liquid Helium or Nitrogen and higher with peak powers up to the mili Watt range. These devices can be obtained as chips on carrier, packaged in a reservoir dewar or in a completely cryogen free ultra silent, low vibration closed cycle cooler system.

Alpes Lasers also offers epitaxial services including InP based MOVPE growth of LEDs, APDs, PINs, QWIPS and other high grade complex heterostructures.
