Alpes Lasers - Model RT-CW-DFB-QCL -Room Temperature Continuous Wave Single Mode Laser
Room Temperature Continuous Wave Single Mode Lasers feature an etched grating in the active region to ensure laser operation at specific wavelengths determined by grating periodicity. This results in single spectral emission with slight wavelength tuning possible via temperature adjustment of the active region. Known for their narrow linewidth, these lasers are ideal for gas sensing applications and can be tuned across a range up to 10 cm-1, supporting various modulation schemes for different applications. Primarily used in spectroscopy, CW-DFB lasers deliver measured performances directly from the submount, with the potential for improvements post-encapsulation. Orders are specification-based rather than serial number-based, requiring detailed requirements upon request.
In a Single Mode Laser, a grating is etched into the active region to force the operation of the laser at very specific wavelength determined by the grating periodicity. As a result, the laser emits on a single spectral setting which may be adjusted slightly by changing the temperature of the active region.
Continuous Single-Mode Lasers have a narrow linewidth which makes them the preferred solution for gas sensing. 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. CW-DFB lasers are mostly used for spectroscopy.
The performances of the lasers shown on this list are as measured directly from the submount. The performances can improve after encapsulation. Orders are made on specification and not with a specific serial number; please make certain to specify your requirements in your requests.
