The optical beam induced current (OBIC) image of a GaAs VCSEL diode is obtained by using a Ti-sapphire laser with a center wavelength λ= 780 nm. The positive and negative pins of the LD is connected with a BNC cable which is then fed to the A/D channel of the scanner to reconstruct the OBIC image. The OBIC image is merged with the reflection image with a scale bar of 10 μm.
Ovelayed image of the dual illumination of a prism via a green laser and a Helium-Neon laser, with two different exposures. For the second image, the camera was panned to add the effect of movement.This photo was taken in the laboratory of Dr. Jean-Claude Diels at the University of New Mexico, and is from the thesis project of Ph.D. candidate James Hendrie.
Scatter light of green and red lasers through a prism.This photo was taken in the laboratory of Dr. Jean-Claude Diels at the University of New Mexico, and is from the thesis project of Ph.D. candidate James Hendrie.
Simultaneous illumination of a large glass prism by a red laser and a green laser. Image was tilted to create movement.This photo was taken in the laboratory of Dr. Jean-Claude Diels at the University of New Mexico, and is from the thesis project of Ph.D. candidate James Hendrie.
This spectrum line, "clock" displays the helium spectrum. or "From infinitesimal to infinite!" Light comes from the atom and goes into the universe. The emission spectrum of helium was visualized using a prism spectrometer. The scale for reading the dispersion angle was projected on the corresponding prism surface. A polar coordinates transformation was then applied to the picture.
The image shows the surprising observation of a visible rainbow of hues in a Near IR continuous wave Raman fiber laser. The laser is pumped only by NIR sources, and there is no visible light input. The visible rainbow is formed due to the 2nd and 3rd harmonic conversion of the cascaded IR Stokes wavelengths traveling in the core of the fiber. The image was captured using a standard DSLR camera, with a 30 second exposure time in the high power lasers lab in CeNSE, IISc.
"The Face" Stimulated Raman Scattering image of a corn stalk. Image acquired by using a Spectra-Physics laser InSight X3, Newport SF-TRU, and Olympus FV 1000 microscope.
The caustic effect observed from a green color water bottle when sunlight falls on one side of the water bottle, light can be converged with dispersion on the other side of the water bottle.
