Coherent Raman scattering imaging of lipid metabolism in cancer
Journal of Innovative Optical Health Sciences, 2023 Cancer cells dysregulate lipid metabolism to accelerate energy production and biomolecule synthesis for rapid growth. Lipid metabolism is highly dynamic and intrinsically heterogeneous at the single cell level.

Label-free evaluation of hepatic microvesicular steatosis with multimodal coherent anti-Stokes Raman scattering microscopy. [PDF]
PLoS ONE, 2012 Hepatic microvesicular steatosis is a hallmark of drug-induced hepatotoxicity and early-stage fatty liver disease. Current histopathology techniques are inadequate for the clinical evaluation of hepatic microvesicular steatosis. In this paper, we explore

Advanced Label-Free Laser Scanning Microscopy and Its Biological Imaging Application
Applied Sciences, 2021 By eliminating the photodamage and photobleaching induced by high intensity laser and fluorescent molecular, the label-free laser scanning microscopy shows powerful capability for imaging and dynamic tracing to biological tissues and cells.

Fourier-transform coherent anti-Stokes Raman scattering microscopy [PDF]
Optics Letters, 2006 We report a novel Fourier-transform-based implementation of coherent anti-Stokes Raman scattering (CARS) microscopy. The method employs a single femtosecond laser source and a Michelson interferometer to create two pulse replicas that are fed into a scanning multiphoton microscope.

Non-linear label-free imaging through a multimode graded index optical fibre [PDF]
EPJ Web of Conferences, 2020 In recent years, great advances have been made in developing minimal footprint micro-endoscopes using multimode optical fibres (MMF) [1]. By employing wavefront shaping methods the seemingly random speckle pattern resulting from the guiding of coherent ...

Synchronized time-lens source for coherent Raman scattering microscopy
Optics Express, 2010 We use the time-lens concept to demonstrate a new scheme for synchronization of two pulsed light sources for biological imaging. An all fiber, 1064 nm time-lens source is synchronized to a picosecond solid-state Ti: Sapphire mode-locked laser by using the mode-locked laser pulses as the clock.
