Waveplate Retardance Metrology: The Basics and Beyond INTRODUCTIONWaveplates are important for the control of the state of polarization and for the measurement of polarization of light. They are modifiers of polarization state but not of the degree of polarization. They do this in a manner described by a parameter called retardance. Most commonly the needed

A Programmable Beam Shaping System for Tailoring the Profile of High Fluence Laser Beams ABSTRACT: Customized spatial light modulators have been designed and fabricated for use as precision beam shaping devices in fusion class laser systems. By inserting this device in a low-fluence relay plane upstream of the amplifier chain, “blocker” obscurations can be programmed

Pulse Shaping Application Note Overview: Quantum computing is a type of computing that uses the rules of quantum physics to process information. Instead of using bits of information (1s and 0s) like a regular computer, quantum computers use qubits, which can represent a 0, a 1, or both at the same time. This makes them

Pulse Shaping Application Note Overview: By modulating the phase and/or amplitude of the spectral component of broadband femtosecond lasers, it is possible to generate arbitrarily shaped ultrafast optical waveforms. Applications for this technology include optical communications, biomedical optical imaging, high-power laser amplifiers, quantum control, and laser-electron beam interactions. The typical implementation utilizes a grating to

Fiber-Based Optical Manipulation Application Note Overview: Fiber optic communications have long been of interest, but more recently the technology is being coupled with SLMs for imaging deep in tissue where scattering would otherwise prevent optical techniques from being practical. Much research is focused on imaging through multi-mode fibers due to the small form factor that

Optogenetics Application Note Overview: Despite extensive research, brain function and neurological diseases are poorly understood. Complexities arise from the quantity of neurons in the brain and from the densely interconnected networks of intermixed cell types. There is a need for methods that non-invasively probe the underlying micro-circuitry in the brain with single-cell resolution…. [dflip id=”7039″][/dflip]
