Calorimeters for measuring the output energy of pulsed ruby and neodymium glass lasers have been built and calibrated.The absorbing medium is an aqueous solution of CuSO4. Calibration of *laser energy detectors has an estimated uncertainty of plus or minus 2% for input energies of 0.1J to 100J.Instrumentation is described that is used for the calibration of cw laser power meters.The calibration unit employs an absorption cell calorimeter to calibrate the output of a photovoltaic cell transfer detector.The calibrations are within an accuracy of 4%.A discussion and description is also given of several types of calorimeters that have been used to measure the output of a 100 watt CO2 laser.The most recent design provides for measurement from 1 watt to 5 kilowatts with a measured accuracy of better than 3%.(Author).

Book Synopsis Power and Energy Measurement of Repetitively Pulsed Lasers by : D. A. Jennings
Download or read book Power and Energy Measurement of Repetitively Pulsed Lasers written by D. A. Jennings and published by . This book was released on 1971 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt:
Calorimeters for measuring the output energy of pulsed ruby and neodymium glass lasers have been built and calibrated. The absorbing medium is an aqueous solution of CuSO4. Calbration of laser energy detectors has an estimated uncertainty of plus or minus 2% for input energies of 0.1J to 100J. Comparisons of absorption cell calorimeters with metal plate calorimeters agree within 1%. Instrumentation is described that is used for the calibration of CW laser power meters. The calibration unit employs an absorption cell calorimeter to calibrate the output of a photovoltaic cell transfer detector. The power meter to be calibrated is then compared to the calibrated output of the transfer detector.

The patent describes a laser power-energy meter which includes a photo-diode acting as a current generator whose output is directly proportional to the optical power incident upon it. The meter provides a direct measurement of optical energy on a per pulse basis on single or repetitive laser pulses by measuring each pulse individually and storing and displaying the energy of the largest received. It also provides a measurement of the power of CW lasers. The measurements are in terms of amount of energy which would enter the human eye. The meter is battery operated and portable.

High Speed Pulse Technology: Volume II: Optical Pulses - Lasers - Measuring Techniques focuses on the theoretical and engineering problems that result from the capacitor discharge technique. This book is organized into three main topics: light flash production from a capacitive energy storage; signal transmission and ranging systems by capacitor discharges and lasers; and impulse measuring technique. This text specifically discusses the air spark under atmospheric conditions, industrial equipment for laser flashing, and claims for light transmitting system. The application of light impulse signal transmission, impulse measurements by means of spark gaps, and conversion factors of various energy units are also described. This publication is recommended for eager electrical engineering and physics students interested in optical pulses, lasers, and measuring techniques.
