Laser Diodes by WavelengthLaser diodes, which are capable of converting electrical current into light, are available from Thorlabs with center wavelengths in the 375 - 2000 nm range and output powers from 0.2 mW up to 2 W. We also offer Quantum Cascade Lasers (QCLs) and Interband Cascade Lasers (ICLs) with center wavelengths ranging from 3.00 to 11.00 µm. Our semiconductor laser diodes come in a variety of packages, including standard Ø5.6 mm and Ø9 mm TO-cans, butterfly, laser pigtail, and chip on submount. QCLs come in Ø9 mm, C-mount, D-mount, and high heat load (HHL) packages, while ICLs are available in HHL packages. We also offer optoelectronics mounts that directly accommodate many of our laser diode package options.
The Laser Diode Selection Guide provides a comprehensive list of all laser diodes available from stock, along with key specifications.
