Alpes Lasers

The Alpes Lasers Beam Combiner is a platform that allows the output beam of two different quantum cascade lasers in standard HHL housing to be combined into a single beam. The system uses fixed optics to rotate the polarization of one of the beam and combines them using a polarizing plate, resulting in a combined beam with the combined power of both original beams. The platform is supplied with both laser housing installed and aligned. The lasers use separate drivers (drivers and temperature controllers sold separately) and can be driven independently or concurrently.

Alpes Lasers manufactures laser diodes emitting at wavelengths from 1.45 to 2.15 μm with powers up to 50 mW. They are offered either as chip-on-carrier or encapsulated in a low power TO-66 package with collimated or divergent free-space beam output.

Alpes Lasers offers single-mode, tunable DFB lasers with wavelengths from 4 to 14 μm and powers up to hundreds of milliwatts. These lasers are able to emit a single wavelength at a time. They can be tuned within a range that can reach up to 10 cm⁻¹; there exists a variety of modulation schemes which can be used for different purposes.

Alpes Lasers offers mid-IR external cavity lasers with wavelengths spanning 4.3 to 14 μm. External cavity kits with integrated laser control electronics are also available. These are Fabry–Pérot lasers designed for maximum width of the gain profile.

Alpes Lasers offers two models of laser safety goggles. The LSG1 is suitable for people not wearing glassed, while the LSG2 is suitable to be worn over a pair of corrective glasses. Both models provide 6+ OD in the mid-IR.

Our broad gain illuminators are Fabry–Pérot lasers designed for maximum width of the gain profile. They can be used as broad spectrum illuminators for spectroscopy or imaging. Combined with an anti-reflection coating, they are suitable for use in an external cavity to obtain a tunable laser with wide tuning range. Their wide and flat gain spectrum can also be suitable to develop frequency combs.

Alpes Lasers offers mid-IR frequency combs centred around 6 μm or 8 μm. The QCL comb is a stand alone device as it integrates the pump laser and the microcavity in its waveguide contrarily to other comb technologies. This makes it a very compact comb source. Being based on QCL technology, comb devices can be manufactured over all the MWIR and LWIR.

At wavelengths between 3.9 and 9.7 μm, Alpes Lasers offers multiple high power Fabry-Pérot lasers up to 1.5 W. These Quantum Cascade Lasers have a minimum average power of 1 W and more than 9 W of peak power. Available in a collimated HHL package with a dedicated driver, these lasers can be used for free-space optical communications, energy deposition, illumination and IR countermeasures.

Alpes Lasers offers QCL laser drivers for pulsed and continuous-wave operation. Pulse widths as low as 20 ns are achievable with repetition rates up to 1 MHz.

Alpes Lasers offers SWIR laser diodes emitting at wavelengths from 1.45 to 2.15 μm with powers up to 50 mW. They are offered either as chip-on-carrier or encapsulated in a low power TO-66 package with collimated or divergent free-space beam output.

Alpes Lasers offers a wide range of lasers with wavelengths ranging from 4 to 14 μm and powers up to several watts. This includes FP, DFB, THz, frequency comb and external cavity lasers in the mid-IR. Additionally, Alpes offers uniquely fast and widely tuneable lasers with our ET and XT product line.

Alpes Lasers designs and manufactures a wide range of different laser types with wavelengths from 4 to 14 μm and powers up to hundreds of milliwatts. This includes FP, DFB, THz, frequency comb and external cavity lasers in the mid-IR. Additionally, Alpes offers uniquely fast and widely tuneable lasers with our ET and XT product line.

Alpes Lasers offers single-mode, narrow-linewidth tuneable DFB lasers with wavelengths from 4 to 14 μm and powers up to hundreds of milliwatts. In CW mode, our DFBs will typically exhibit linewidths on the order of MHz.

Alpes Lasers offers pulsed QCLs with wavelengths ranging from 4 to 14 μm and average powers up to hundreds of milliwatts. The unique nature of QCLs makes them perfectly suited for very short-pulse applications.

This includes FP, DFB, THz, frequency comb and external cavity lasers in the mid-IR. Additionally, Alpes offers uniquely fast and widely tuneable lasers with our ET and XT product line.

Alpes Lasers designs and manufactures semiconductor lasers, particularly quantum cascade lasers, with wavelengths from 4 to 14 μm and powers up to several watts. These lasers are highly compact and efficient, making them ideal for applications in the mid-IR with strict size constraints.

Alpes Lasers designs and manufactures single-mode mid-IR lasers with wavelength tuning of up to 40 cm^-1. We offer fast tuning over a wide range of wavelengths with our QC-ET product line, and extremely wide tuning with our QC-XT lasers.

Alpes Lasers designs and manufactures single-mode mid-IR lasers with wavelength tuning over more than 10 cm⁻¹. Broad-gain lasers with wide tuning in an external cavity are also offered.
