Ames Photonics: Si Photodiodes and ultrashort laser pulses


Recently, Ames Photonics have investigated the feasibility of using silicon photodiodes, like their Oculus USB photodetector, for detecting femtosecond laser pulse energy output.

Silicon photodiodes offer potential advantages for the detection of ultrashort laser pulses. However, until now, no reliable information about saturation energy level, practical energy density and linearity of photodiodes under ultra-short laser pulse exposure has been available in the literature.

The results show that Si photodiode have several advantages compared to other commonly used photosensors, including:

  • Excellent linearity of output current as a function of incident light
  • Very high sensitivity-can typically resolve pJ levels
  • Spectral response from 190 nm to 1100 nm (Si), longer wavelengths with other semiconductor detectors

Edmund Optics Image Rotation Prisms

Half  Penta Prisms

Edmund Optics TECHSPEC® Half Penta Prisms are used to deviate the line of sight by 45° without inverting or reverting the image. The reflecting surface is aluminized and over-coated with Inconel and black paint to increase the prism's efficiency. When combined with a corresponding TECHSPEC® Schmidt Prism, a Pechan Prism pair is formed. The Pechan Prism will invert or revert the image while not deviating the line of sight. The Pechan prism can be placed in converging or diverging light allowing for system size reduction.

Edmund Optics Deformable Mirrors correct spherical aberration

Edmund Optics

Edmund Optics , the premier provider of optical components, has introduced new high performance Deformable Mirrors. These mirrors are the easiest and most convenient tool to correct optical aberrations through wavefront manipulation and control. They are ideal for use in combination with wavefront sensors and real-time control systems in adaptive optics. This particular deformable mirror has 32 radially packed actuators. There is more than 10µm (typically 14µm) of actuator max stroke. They are suited for tabletop applications as well as OEM integration. Priced considerably less than competing products, EO’s Deformable Mirrors are in-stock and available for immediate delivery for fast turnaround and excellent value.

These versatile mirrors will be featured in a special demonstration available for viewing at the EO Booth 1909 during CLEO/QELS 2010, May 18-20, 2010 at the McEnery Convention Center in San Jose, CA. The demonstration will show the integration of a deformable mirror into a PBS-based Twyman-Green Interferometer. By replacing the traditional test surface with a deformable mirror, one can better illustrate the deformations of the mirror’s surface. These small changes in the surface of the mirror create variations in the interferogram. Additionally, this set up highlights how optical noise can be reduced by simply reducing the amount of back reflections in the system.
