Stabilized

HeNe Laser

SL03-Series

Design and Operation

Our SL 03-Series stabilized HeNe lasers employ a patented dual longitudinal mode stabilization technique providing high

frequency and amplitude stabilities, low optical feedback, and extremely rapid warm-up. They consist of a compact

cylindrical head incorporating the laser tube, plus a separate table-top housing incorporating a high-voltage supply and

control electronics equipped with a front-panel switch for selecting frequency-stabilized or amplitude-stabilized mode of

operation. An internal thread at their beam exit provides a rigid mounting for mechanical shutters or various types of

optical components. Fiber couplers mating to singlemode or multimode fibers are available as an option.

Major Features and Benefits

High frequency and amplitude stabilities

Choice of two modes of operation, frequency

stabilized or amplitude stabilized

Rapid warm-up (typically 10 min)

Compactly designed

Laser heads come equipped with an internal thread

at their beam exit for installing, e.g., fiberoptic

couplers, as standard.

All units bear the CE-symbol certifying compliance

with EG-Guidelines 73/23/EWG and 89/336/EWG

and harmonized EN-Standards EN 61010-1,

EN 60825-1, EN 55011, and EN 50082-1.

Options
