Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Measurement of Pulsed-Laser Power We describe calibrating several Optical-pulse power meters to an accuracy of about 82 or better. The meters are designed for Q-switched neodymium lasers with peak powers in excess of a few megawatts and pulses longer than five or ten nanoseconds. Combined with a fast oscilloscope or a transient digitizer, the meters display the time-domain waveform of the laser emission and thereby allow determination of Parameters such as transition duration (risetime, falltime), duration and peak power. We discuss calibrating the meters by both pulsed and cw methods, and show why each method is useful as a check on the other. We treat in some detail the effect of speckle on the use of diffusers as attenuators in power-meters such as ours.

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. 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).

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Electrical Engineering Introduction to Laser Technology, Third Edition Would you like to know how a laser works, and how it can be modified for your own specific tasks? This intuitive third edition-previously published as Understanding Laser Technology, First and Second Editions-introduces engineers, scientists, technicians, and novices alike to the world of modern lasers, without delving into the mathematical details of quantum electronics. It is the only introductory text on the market today that explains the underlying physics and engineering applicable to all lasers. A unique combination of clarity and technical depth, this book begins with an introductory chapter that explains the characteristics and important applications of commercial lasers worldwide. It proceeds with discussions on light and optics, the fundamental elements of lasers, and laser modification. The concluding chapters are composed of a survey of modern lasers, including: Semiconductor lasers Optically pumped solid-state lasers Ion, HeNe, and HeCd lasers Carbon dioxide lasers Excimer lasers (codiscovered by J. J. Ewing) Ultrafast and tunable lasers, OPOs Introduction to Laser Technology, Third Edition is intended for those who are familiar with the principles of electro-optical technology, but possess limited formal training. This comprehensive treatment is essential, one-stop shopping for professionals, students, and non-engineer executives interested in the design, sales, or applications of the laser and electro-optics industry.

Book excerpt: The Frequency-Resolved Optical-Gating (FROG) technique has revolutionized our ability to measure and understand ultrashort laser pulses. This book contains everything you need to know to measure even the shortest, weakest, or most complex ultrashort laser pulses. Whether you're an undergrad or an advanced researcher, you'll find easy-to-understand descriptions of all the key ideas behind all the FROG techniques, all the practical details of pulse measurement, and many new directions of research. This book is not like any other scientific book. It is a lively discussion of the basic concepts. It is an advanced treatment of research-level issues.

Available in PDF, EPUB and Kindle. Book excerpt: Ultrashort Laser Pulse Phenomena, Second Edition serves as an introduction to the phenomena of ultra short laser pulses and describes how this technology can be used to examine problems in areas such as electromagnetism, optics, and quantum mechanics. Ultrashort Laser Pulse Phenomena combines theoretical backgrounds and experimental techniques and will serve as a manual on designing and constructing femtosecond ("faster than electronics") systems or experiments from scratch. Beyond the simple optical system, the various sources of ultrashort pulses are presented, again with emphasis on the basic concepts and how they apply to the design of particular sources (dye lasers, solid state lasers, semiconductor lasers, fiber lasers, and sources based on frequency conversion). Provides an easy to follow guide through "faster than electronics" probing and detection methods THE manual on designing and constructing femtosecond systems and experiments Discusses essential technology for applications in micro-machining, femtochemistry, and medical imaging

Download or read book Laser Power Energy Meter written by George A. Rex and published by . This book was released on 1972 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
