Semiconductor laser confocal and interference microscopy

Optics Communications, 1996
We describe a semiconductor laser confocal microscope which has the capability to produce both confocal and interference images. This versatility is achieved by using different lasing regimes of the laser, which are controlled by its injection current.

New possibilities of studying microbial objects by laser interference microscopy

Biophysics, 2011
A novel method, laser interference microscopy, has been developed for studying the morphofunctional state of bacterial cells and the structure of bacterial communities. The following potentialities of the method are shown: rapid determination of the cell structure and subcellular structures (nucleus zone, vacuoles, lamellar structures) and the ...

Laser-based modulation-interference microscopy of optical surfaces

Journal of Optical Technology, 2012
A new version of the modulation interference microscope with a long-path coordinate stage on aeromagnetic guides has been developed that can displace the microscope with nonrectilinearity no greater than 0.1 µm on a path length of up to 300 mm. The given modification of the microscope can be used to investigate the surface of large optical items having

Study of Regular Intracellular and Membrane Processes in Neurons by Laser Interference Microscopy

Bulletin of Experimental Biology and Medicine, 2005
Regular fluctuations in the height of phase profile of isolated neuron were studied by laser interference microscopy. The resultant spectra of frequencies of changes in the phase profile height indicate regular local changes in the optical density and/or geometry of neurons.

Comparative study of the dynamics of laser breakdown in water and hexane using interference microscopy

Quantum Electronics, 2021
Abstract The changes in the optical properties of water and hexane under femtosecond irradiation (Ti : Al2O3 laser, wavelength 800 nm, intensity ∼1013 W cm−2) are investigated in the cavitation (bubble-formation) regime using interference microscopy in a time interval of ∼1.5 ns since the impact onset.

Peculiarities of studying an isolated neuron by the method of laser interference microscopy

Quantum Electronics, 2006
Actual aspects of using a new method of laser interference microscopy (LIM) for studying nerve cells are discussed. The peculiarities of the LIM display of neurons are demonstrated by the example of isolated neurons of a pond snail Lymnaea stagnalis. A comparative analysis of the images of the cell and subcellular structures of a neuron obtained by the

Assessing the Functional State of Red Blood Cells by Using the Laser Interference Microscopy

Cell and Tissue Biology, 2021
The potential of laser interference microscopy was assessed for noninvasive examination of the morphofunctional state of peripheral blood erythrocytes exposed in vitro to adrenaline (10–9 g/mL), cortisol (5 × 10–7 g/mL), propranolol beta-blocker (10–9 g/mL), and glutaraldehyde (0.1%).

Interference microscopy of femtosecond laser written waveguides in phosphate glass

Applied Physics B, 2009
By focusing fs-laser radiation in the volume of a transparent material the refractive index can be changed locally, leading to 3-dimensional waveguiding structures. Waveguides are written in phosphate glass (IOG from Schott) at a depth of 100 μm below the surface. The pulse energy and the scan velocity are varied.

X-Ray Laser Interference Microscopy for Advanced Studies of Laser-Induced Damages

2007
We show results obtained using XUV interference microscopy to observe in situ nanometer-scale modifications of optical surfaces exposed to intense sub-ns laser pulses. The surface was irradiated by a blue “damaging” laser (438 nm) and diagnosed by a soft X-ray laser based on neon-like zinc, emitting at 21.2 nm. Investigated objects were thin plane beam-
