Laser Spectroscopy Customer Case An academic researcher is studying the attenuation properties of different materials inside Laser cavities for applications in Laser Spectroscopy. The Laser pulses are generated by one Laser, and are then transmitted by mirrors into another cavity filled with gaseous material. In the second cavity, the light pulses are continuously reflected by opposite mirrors and their intensities are measured by a transducer which converts them into decaying pulses of 30 nanosecond width. The decay takes about 40 microseconds to settle. The researcher is required to capture the decaying pulses and save the captured data onto the [...]

Laser Transient Absorption Spectroscopy Customer Case The customer's setup is a scientific application in which transient signals from a Laser Absorption Spectroscope are transferred to a computer. The laser power is modified in steps and the process is repeated. The measurement sensitivity is limited by noise generated by the current digitizer. The customer wants to capture and continuously average very small pulse responses. The lowest signal pulse height is 0.5 milliVolts and can range up to 2 mV. The duration of each response pulse is 1 to 10 microseconds. The Pulse Repetition Frequency (PRF) is 10 Hz. The customer's [...]

Laser Measurement & Characterization of Flat Panel Displays Customer Case This customer's application involves the characterization of flat panel displays (used in laptop computers, computer game displays, etc.) via laser scanning. The laser is bounced off a number of mirrors and then through lenses, from which it is scattered. The scattered laser light must then be analyzed in order to determine the quality of the flat panel display. This laser measurement system is used not only by flat panel display industries, but also by disk drive manufacturers to analyze platter quality and, in the near future, for characterizing silicon [...]

Laser Signals Striking Silicon-Diode Target Customer Case The customer wants to capture the output of some silicon diodes looking at a laser target. The typical signal is anywhere from 20mv to 1V in amplitude and 0 to 15ns in length. There are up to 16 of these diodes that are looking at the same target. Each diode has a different filter so the post-trigger depth and amplitude-scale must be user-adjustable. Their main interest is to sample and digitize the signals for archiving, with later retrieval and plotting. Fancy software is not needed for display as the data is gathered [...]
