Stabilized HeNe Laser
SL 02-Series
Design and Operation
SL 02-Series stabilized HeNe lasers employ a two-mode stabilization technique providing high frequency stability in conjunction with rapid warm-up. The laser is characterized by a compact cylindrical design. For the power supply only a single 13.5 V-AC adapter is necessary. The output beam is linearly polarized. Two different models, either with one single mode (Model SL 02/1), or with two polarized modes (Model SL 02/2) are available. An internal thread at the beam exits may be used for installing mechanical shutters or various types of optical components. Fiber couplers with pigtails mating to singlemode or multimode fibers are available as an option.
