Alpes Lasers introduces the GLIDER widely tunable mid-IR light source. Based on a external cavity design, the Glider is a monolithic all-in-one light source that requires no assembly or external drivers. The optical output is a single-beam of light whose wavelength can be selected within a range of up to ~2200 cm –1 . Alpes Laser’s GLIDER is designed for single-mode operation with wide spectral tunability.

The Glider consists of single or multiple quantum cascade laser (QCL) gain chip, a grating-tuned extended optical cavity in Littrow configuration, driver electronics and control software. The system is delivered fully assembled in a closed housing and requires no alignment. The Glider is available in either a single module configuration or in a multi-module configuration. The multi-module configuration can accommodate up to 4 different modules for larger coverage. The system comes with a controller providing a Web based graphical user interface allowing access to all the functionalities of the system. OEM version of the modules can be offered on demand for integration. The graph below showcases the range covered by different chips that can be used in the Glider system in dotted lines and the direct emission range in full lines. The bottom row shows a series of chips that can be used to cover the entire range, and over these other chips may be used to reach a particular range better.

The following table lists the specific performance of the Broad Gain lasers shown in pulsed mode (except BG-3.2-3.6 which operates CW). Only the tuning range and minimum power over the tuning range are part of the specification; the typical tuning curve is shown as an example and each laser will have a different tuning curve.

Furthermore, standard Fabry-Perot lasers with a narrower gain can also be compatible with the ECLK. You can see here a small subset of the performances available. For performances at other wavelengths, write to us to request testing!
