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.
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
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
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
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
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
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
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
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-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.
