I am trying to get a sample read out from a laser diode on an oscilloscope. I get a good pulse signal if I shine my keychain flashlight on the detector, but a very noisy signal from the diode itself. What could be causing the noise in this system?
Laser Optics Lab:Specifications for Selecting a Laser
When determining which laser to use for your application, consider the following specifications: wavelength, coherence length, beam divergence, and Rayleigh range.
Learn the key parameters that must be considered to ensure you laser application is successful. Common terminology will be established for these parameters.

Laser Polarization: The Importance of Polarization in Laser Applications
Understanding the polarization of laser light is critical for many applications, as polarization impacts reflectance, focusing the beam, and other key behaviors.
A Guide to (Not Over) Specifying Losses in Laser Optics
Overspecifying optical losses in laser systems will not further improve your performance or reliability, but it could cost you additional money and/or time.
Learn why the bulk laser-induced damage threshold (LIDT) of glass is significantly different than the LIDT optical components with coatings, such as AR thin films.
