sl 02-Series stabilized HeNe lasers employ a patented two-mode stabilization technique providing high frequency
stability in conjunction with rapid warm-up. The stabilized HeNe laser is installed in a compact cylindrical case. 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 directly installed on the laser head have the advantage of stable and nearly alignment-free operation. Couplers
with pigtails mating to singlemode or multimode fibers are available as an option.
