Page 4: Part 1. Safety
• Operating this product in the presence of flammable gases or fumes is extremely hazardous. • Disconnect the power cord before replacing fuses. • Clean the laser head and power supply with a dry, soft cloth. Do not use liquids. 12112-S01 Rev B, August 30, 2010 Page 4 www.thorlabs.com... -
Page 5: Ce Compliance
CE requirements. In order for the CE regulations to be met, all Thorlabs power supplies must be used with an input line cord with a length of less than three meters. The factory-included line cord has a length of approximately two meters. Other cords may be used, but they must have a length of no longer than three meters in order for the laser system to remain CE compliant. -
Page 6: Part 2. Description
Tunable HeNe Laser System Part 2. Description Thorlabs’ high-power red (632.8) Helium-Neon gas lasers have a maximum stable output power of 50.0 mW and a fundamental Gaussian beam. The laser comes in two versions, one for 115 VAC and another for 220 VAC voltage source. The output beam is linearly polarized. -

Systems one end of the laser tube, and an output coupler mirror with approximately 1% transmission at the other end. 12112-S01 Rev B, August 30, 2010 Page 7 www.thorlabs.com... -
Page 8: Hene Linewidth
Transmission at Output Coupler (OC) HeNe lasers tend to be small, with cavity lengths of around 15 cm up to 0.5 m and optical output powers ranging from 1 mW to 100 mW. Thorlabs offers output powers up to 50 mW. HeNe Linewidth A red HeNe laser wavelength is 632.816 nm in air, though it is often reported as either 632 nm or... -

From these states, the electrons quickly decay to the ground state. The HeNe laser’s power output is limited because the neon upper level saturates with higher current, while the lower level varies linearly with current. 12112-S01 Rev B, August 30, 2010 Page 9 www.thorlabs.com... -
Page 10: Hene Polarization
Depending on the time scale of an application, large power fluctuations are possible. Polarized Beam The state of polarization in a polarized HeNe laser beam is linear, making these lasers ideal for polarization-sensitive applications. 12112-S01 Rev B, August 30, 2010 Page 10 www.thorlabs.com... -

Then remove the two top screws from the rear panel of the laser. Remove these screws last. Remove these screws first. 3. Carefully remove the top cover and the front plate from the laser housing. 12112-S01 Rev B, August 30, 2010 Page 15 www.thorlabs.com... - Page 16 7. Rotate the color selector knob to ensure that all wavelengths are present. If not, ensure that the system is tuned to its optimal power. If all wavelengths are still not present, repeat steps 5 and 6 again. 12112-S01 Rev B, August 30, 2010 Page 16 www.thorlabs.com...
- Page 17 14. Verify that the alignment marks on the two adjustment knobs have not changed. If they have, annotate in this manual their present turn values by turning each one clockwise until they stop and then counting the number of turns until the new alignment is reached. 12112-S01 Rev B, August 30, 2010 Page 17 www.thorlabs.com...

However, any polarization optics in the path (intentional or unintentional) can cause large variations in the output power. These applications should only be used with a polarized laser. 12112-S01 Rev B, August 30, 2010 Page 18 www.thorlabs.com... -
