Safety Information 2.1.1. Safety Summary As defined by the Federal Register 21 CFR 1040.10 Laser Safety Standard, Thorlabs’ Helium Neon laser heads are classified according to output power and wavelength. In compliance with this standard, certain performance features and laser safety labels are provided on the product. - Page 6 The parameters for the laser system are outlined in the table below, followed by classification warning labels. See specification tables for classifications specified by the Center for Devices and Radiological Health (CDRH), a division of the Food and Drug Administration (FDA).

Page 7: Safety Instructions
Thorlabs’ assumes no liability for the customer’s failure to comply with any of these safety requirements. - Page 8 Red HeNe Laser Systems Chapter 2: Safety Warning To avoid the risk of injury or death, always observe the following precautions before initializing the unit: Never look into the end of an optical cable connected to an optical output device that is operating. Laser radiation is invisible, and direct exposure can severely injure the human eye.

Page 9: Chapter 3 Description
Chapter 3 Description Thorlabs’ line of cylindrical, high-power, red (632.8 nm) helium-neon (HeNe) gas lasers have stable output powers from 10.0 to 22.5 mW and a fundamental Gaussian beam. Depending on the model chosen, the output beam will be either linearly polarized or randomly polarized (unpolarized). The state of polarization in a randomly polarized laser beam is not truly an unpolarized source, but rather a single state of polarization that changes on a small timescale. -
Page 10: 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 22.5 mW. 3.3.1. HeNe Linewidth A red HeNe laser wavelength is 632.816 nm in air, though it is often reported as either 632 nm or 633 nm. - Page 11 Red HeNe Laser Systems Chapter 3: Description Neon Gain Curve FWHM ~1.5 GHz Lasing Lasing Threshold Cavity Modes Frequency FSR ~1000 MHz FSR ~200 MHz Short (0.2 m) Laser Long (1 m) Laser Figure 2 HeNe Gain Curve Showing Cavity Modes The laser process in a HeNe laser starts with the collision of electrons from the electrical discharge with the helium atoms in the gas.

Red HeNe Laser Systems Chapter 3: Description including a green (543.365 nm, sometimes called GreeNe laser), a yellow (593.932 nm), a yellow-orange (604.613 nm), and an orange (611.802 nm) transition. The typical red, 633 nm wavelength output of a HeNe laser actually has a much lower gain compared to other wavelengths, such as the 1.15 μm and 3.39 μm lines. -

Page 18: Noise, Oscillations, And Fluctuation Sources
Red HeNe Laser Systems Chapter 6: Troubleshooting 6.2.1. Noise, Oscillations, and Fluctuation Sources There are many sources of noise, oscillations and fluctuations of the output of a HeNe laser. One of the most common is from longitudinal modes drifting into and out of the gain curve. The frequency of these fluctuations vary from less than a Hz to as high as several kHz, depending on the stability of the environment. -
