Thorlabs' pigtailed butterfly laser diodes are housed in type 1, 14-pin butterfly packages to provide compatibility with any standard 14-pin laser diode mount. This selection includes Fabry-Perot (FP), Fiber-Bragg-Grating (FBG) stabilized, and Volume Holographic Grating (VHG) multimode fiber pigtail lasers. The VHG lasers with a multimode fiber pigtail are ideal for applications requiring high powers. We also offer single-frequency lasers (SFLs) with Distributed Bragg Reflector (DBR), VHG, External Cavity (ECL), and Distributed Feedback (DFB) designs.
