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. 12097-D02 Rev C, August 31, 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
Red HeNe Laser System Part 2. Description Thorlabs’ red (632.8 nm) Helium-Neon gas lasers have a maximum stable output power ranging from <1.0 to 2.0 mW and a fundamental Gaussian beam. The laser comes in two versions. One with linearly polarized output beam and the other with a randomly (unpolarized) polarized output beam.
Page 7: Hene Laser Overview
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...

Page 9: 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. 12097-D02 Rev C, August 31, 2010 Page 9 www.thorlabs.com...
Page 10: Part 3. Unpacking
The equipment included in this shipment should match the packing slip attached to the box. Verify that the correct product was shipped to you by matching the item number on the box. If the shipment is incomplete, or if an incorrect item was shipped to you, please notify Thorlabs immediately. This package should contain: •...
Page 11: Part 4. Set-Up
Failure to plug the connector all the way in can result in the laser failing to lase or arching and damage to the power supply or laser head. 12097-D02 Rev C, August 31, 2010 Page 11 www.thorlabs.com...
Page 12: Part 5. Operation
20 sec after turning the power on, you can turn the unit off and then back on again. This will not damage the laser. Be sure to give enough time to allow the CDRH safety delay to elapse before turning the system off and on. 12097-D02 Rev C, August 31, 2010 Page 12 www.thorlabs.com...
Page 13: Part 6. Troubleshooting
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. 12097-D02 Rev C, August 31, 2010 Page 13 www.thorlabs.com...
