A Programmable Beam Shaping System for Tailoring the Profile of High Fluence Laser Beams

Spatial Light Modulator Resources /

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 […]

Meadowlark Optics Has Pivotal Role in Fusion Research

News /

The Beginning    Back in 1952, the first useful demonstration of nuclear fusion was carried out.  It was for vastly different reasons than those celebrated most recently, although one might say that was when interest in atomic science for practical applications really blew up (pun intended.) Physicists have been seeking fusion as a viable energy source ever since, with

Pulse Shaping Application Note

Spatial Light Modulator Resources /

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

Holographic Optical Tweezing (Hot) Application Note

Spatial Light Modulator Resources /

Holographic Optical Tweezing (Hot) Application Note Overview: Holographic optical tweezing uses tightly focused laser beams to manipulate the 3D position of objects within a field of view. This can be used for research in fundamental physics, biological studies, and cold atom trapping. The SLM is used to modulate the phase of an incident laser beam

Fiber-Based Optical Manipulation Application Note

Spatial Light Modulator Resources /

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

Spatial Light Modulator Resources /

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…. Use the

Volumetric Imaging Application Note

Spatial Light Modulator Resources /

Volumetric Imaging Application Note Overview: In order to understand biological functions at a system level it is necessary to imageinterconnectivity of processes in real time. This is particularly relevant in neuroscience, where the BRAIN initiative is funding research to understand how the brain functions, and how that function is altered by disease. This requires imaging
