Q-switched, solar-pumped, high power Nd:YAG lasers are attractive for a variety of applications requiring high instantaneous peak power density. The Q-switching can be obtained by an acousto-optic, electro-optic or passive device. Passive Q-switching seems an excellent choice for space as well as for other applications since it neither requires an external driver nor an electrical power supply. In recent years Cr⁺⁴:YAG single crystals were extensively used as passive Q-switches for flashlamp-pumped high power Nd:YAG lasers, demonstrating their superior thermal superior thermal characteristics and durability. In this work we report the first operation of passive Q- switched, solar-pumped, high power Nd:YAG lasers. The concentrated solar energy for he optical pumping of the laser was obtained by a 3-stage combination of imaging and non-imaging optics. It included: i) Weizmann Institute solar tower heliostats, ii) 3D compound parabolic concentrator, and iii) 2D compound parabolic concentrator in which the laser rod was placed. 72 mm long laser rods with either 3 mm or 4 mm diameter were used. The passive Q-switch was made from a Cr$=+4):YAG single crystal having a low- intensity transmission of 72 percent at 1.06 (mu) . Its rear surface was coated by a high reflectivity coating, serving as the rear mirror of the cavity. Output coupling mirrors with various reflectivities were used. The passive Q-switch demonstrated excellent durability and reliability during all the experiments. Repetition rates of 6-39 kHz were measured, showing higher repetition rates at higher laser power levels. The pulses demonstrated shorter full width at half maximum (FWHM) time for higher laser power elves, and the FWHM time range was 190-310 nsec. The maximal measured average power was 14 W. Thermal lensing was measured as a function of the absorbed solar power in the laser rod. It is estimated that laser peak power densities of approximately 100 kW/cm² were achieved in the experiments. It is believed that near-future modifications may improve this value appreciably.

CCD camera baseline calibration and its effects on imaging processing and laser beam analysis Paper

Carlos B. Roundy

Proceedings Volume 10th Meeting on Optical Engineering in Israel, (1997) https://doi.org/10.1117/12.281394

Read Abstract +

CCD cameras are commonly used for many imaging applications, as well as in optical instrumentation applications. These cameras have many excellent characteristics for both scene imaging and laser beam analysis. However, CCD cameras have two characteristics that limit their potential performance. The first limiting factor is the baseline drift of the camera. If the baseline drifts below the digitizer zero, data in the background is lost, and is uncorrectable. If the baseline drifts above the digitizer zero, than a false background is introduced into the scene. This false background is partially correctable by taking a background frame with no input image, and then subtracting that from each imaged frame. ('Partially correctable' is explained in detail later.) The second characteristic that inhibits CCD cameras is their high level of random noise. A typical CCD camera used with an 8-bit digitizer yielding 256 counts, has 2 to 6 counts of random noise in the baseline. The noise is typically Gaussian, and goes both positive and negative about a mean or average baseline level. When normal baseline subtraction occurs, the negative noise components are truncated, leaving only the positive components. These lost negative noise components can distort measurements that rely on low intensity background. Situations exist in which the baseline offset and lost negative noise components are very significant. For example, in image processing, when attempting to distinguish data with a very low contrast between objects, the contrast is compromised by the loss of the negative noise. Secondly the measurement of laser beam widths requires analysis of very low intensity signals far out into the wings of the beam. The intensity is low, but the area is large, and so even small distortion can create significant errors in measuring beam width. The effect of baseline error is particularly significant on the measurement of a laser beam width. This measurement is very important because it gives the size of the beam at the measurement point, it is used in laser divergence measurement, and it is critical for realistic measurement of M², the ultimate criterion for the quality of a laser beam. One measurement of laser beam width, called second moment, or D4(sigma) , which is the ISO definition of a true laser beam width, is especially sensitive to noise in the baseline. The D4(sigma) measurement method integrates all signals far out into the wings of the beam, and gives particular weight to the noise and signal in the wings. It is impossible to make this measurement without the negative noise components, and without other special algorithms to limit the effect of noise in the wings.

This paper describes a series of promising optical diagnostic techniques to provide a comprehensive acquisition of the optical information from various flow fields under investigation. A simultaneous application of the two or even several diagnostic techniques which combines a CFD code calculations yield more accurate measurements of the density and/or the density gradient distributions in complex flow fields. Traditionally qualitative data of the density gradient in a high speed compressible flow have been obtained by schlierengraphy. A white light source and a laser two optical arms schlieren optical schemes were constructed on the base of a conventional schlieren system. The optical image of a model was focused on a photo film and projected on a screen. A CCD- camera was used to catch the focused image in real time, to display it on a control monitor and to record it on a video tape recorder. An acoustically stable holographic variable shear interferometer, which has been easily constructed on the base of the conventional schlieren system allowed to record a signal hologram during the wind tunnel run by using a continuous wave laser light source. Signal and comparison holograms have then been post-processed by the dual hologram technique to display shearing interferograms. A holographic Moire deflectometry method is presented. The holographic recording provides a 'freezing' of the distorted signal wave on a hologram to analyze it a posteriori by the Moire technique. A novel holographic Moire interferometer is described and its application to testing a small size axisymmetric supersonic air jet is shown. An interference method with enhanced sensitivity and compensating for optical aberrations, which is based on rerecording holograms is briefly described. It would provide a reliable acquisition of the phase information from wide range of weak phase objects including high speed low density flow fields. The method has been demonstrated by mapping the density field of the supersonic air jet as a representative weak phase object. The numerical analysis of a 2-D flow field was also carried out by means of computational fluid dynamics (CFD) methods.
