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 1.5 mW up to 3 W. We also offer Quantum Cascade Lasers (QCLs) with center wavelengths ranging from 4.05 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 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.
