Fiber Optic Coupling

Technical Notes

The problem of coupling light into an optical fiber is really two separate problems. In one case, we have the problem of coupling into multimode fibers, where the ray optics of the previous section can be used. In the other case, coupling into single...

Optics Formulas

Technical Notes

Light is a transverse electromagnetic wave. The electric E and magnetic M fields are perpendicular to each other and to the propagation vector k, as shown below. Power density is given by Poynting’s vector, P, the vector product of E and H. You can e...

How to Clean Optics

Technical Notes

Dust and stains on Optics can cause scattering, and impurities on the optic surface can react with incident laser light to damage optical coatings. With proper handling and cleaning of your optics, you can prevent damage and ensure their continued pe...

Linear Translation Stage Terminology

Technical Notes

This glossary covers important terms related to linear translation stages.

Introduction to Laser Frequency Stabilization

Application Notes

The steps outlined in this application note can be used to stabilize a TLB-7000, TLB-6900, or TLB-6300 series tunable diode laser to a reference cavity using the Pound-Drever-Hall stabilization technique.

Motion Basics Terminology & Standards

Technical Notes

The function of a stage is to constrain motion to a desired direction. For a linear stage, the desired motion is along an ideal straight line. Any motion in a constrained direction will contribute to deviation from the ideal trajectory and/or positio...

The Michelson Interferometer Experimental Setup

Application Notes

Albert A. Michelson won the 1907 Nobel Prize in Physics “for his optical precision instruments and the spectroscopic and metrological investigations carried out with their aid.” One of his instruments was the Michelson interferometer. The Michelson i...

Introduction to Positioning Equipment


This tutorial introduces opto-mechanical component design basics and will familiarize the reader with the issues that need consideration in the selection of the most commonly used tabletop components. It emphasizes practical issues, not mathematical ...

Laser Damage Threshold

Technical Notes

For continuous wave (CW) lasers the damage threshold can be calculated from the peak power and beam diameter. For example, to calculate the power density of a 50 mW Nd:YAG laser at 1064 nm with a 0.8 mm beam diameter, first calculate the beam area in...
