Introduction to Laser Frequency Stabilization

 Application Note
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.

Practical Uses and Applications of Electro-Optic Modulators

 Application Note
Electro-optic amplitude and phase modulators allow you to control the amplitude, phase, and polarization state of an optical beam electrically. For instance, in communications systems, these modulators impress information onto an optical frequency ca

A Survey of Methods Using Balanced Photodetection

 Application Note
New Focus balanced photoreceivers are ideal for optical detection applications that require sensitive measurements. This application note focuses on several techniques, divided into three categories: small signal detection in time domain, small signa

The Michelson Interferometer Experimental Setup

 Application Note
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

FM Spectroscopy With Tunable Diode Lasers

 Application Note
Frequency-modulation spectroscopy is a powerful tool that can achieve high sensitivities with a relatively simple experimental setup. Tunable diode lasers, in particular, can make the setup even simpler because they provide a narrow, tunable output t

Phase-Shifting Interferometry for Determining Optical Surface Quality

 Application Note
Determining the surface quality of a critical component—the deviation from the intended shape whether flat, spherical, etc.—is crucial to high-precision manufacturing. Traditional methods consist of an interferometer, for example a Twyman-Green interf

Insights into High-Speed Detectors and High-Frequency Techniques

 Application Note
With the advancement of high-transmission-rate systems and short-pulse lasers, many applications now require high time-resolution or equivalently, high frequency-bandwidth optical detection. For example, a high-speed photodetector can measure the fre

Phase and Amplitude Modulator Applications

 Application Note
Resonant phase modulators are the ideal component to use in a Pound-Drever-Hall laser frequency stabilization system. This optical FM frequency discriminator technique is used to lock the optical frequency of a laser to a stable Fabry-Perot reference

Vacuum-Compatibility and Ultraclean Applications

 Application Note
For applications requiring ultraclean devices or operation in high-vacuum, our vacuum-compatible Picomotor™ actuators and Stability™ mounts offer “quantified exceptional” performance. We characterize all our vacuum components using standard Gas Chroma

Photo-Biological Testing with UV Solar Simulators

 Application Note
Photo-biology is the study of the effect of UVA and/or UVB, visible, and IR radiation upon living systems. The first law of photochemistry (Grotthaus-Draper Law) states that light must be absorbed for a photochemical event to occur.
