Thorlabs offers HeNe lasers with output powers ranging from 0.8 mW to 22.5 mW at 632.8 nm (red) and with either a fixed linear or fluctuating output beam polarization. We also offer stabilized HeNe lasers, which allow for either frequency or intensity stabilization. Mounting solutions for these HeNe lasers include a clamp mount, cage system mount, a kinematic V-mount, and fiber and SM-threaded adapters.
