Transform-limited pulse generation in normal cavity dispersion erbium doped single-walled carbon nanotubes mode-locked fiber ring laser
We demonstrate an erbium doped fiber ring laser mode-locked with a carboxymetylcellulose high-optical quality film with dispersed single-walled carbon nanotubes (SWCNT). The laser with large normal net...
PublicationsPicosecond pulse compression by means of soliton effects in single-mode silica glass fiber in the 2 m spectral range
We report on the soliton-effect compression dynamics in single-mode SMF-28 fiber of picosecond pulses generated by an all-fiber MOPA-source based on a mode-locked thulium-doped fiber oscillator with an...
PublicationsA high power MOPA-laser based on a mode-locked thulium-doped fiber oscillator with intracavity dispersion management
We present a mode-locked thulium-doped fiber laser with intracavity group velocity dispersion (GVD) management by incorporating a low-loss single-mode germanium–silica fiber that introduces a significant...
PublicationsNonlinear Amplifying Loop-Mirror-Based Mode-Locked Thulium-Doped Fiber Laser
We present an SESAM mode-locked thulium-doped fiber laser incorporating nonlinear amplifying loop mirror with intracavity and external group velocity dispersion control, which generates sub-300-fs near-transform-limited...
PublicationsA correlation study of layer growth rate, thickness uniformity, stoichiometry, and hydrogen impurity level in HfO2 thin films grown by ALD between 100 °C and 350 °C
Hafnium oxide was deposited from tetrakis(dimethylamino)hafnium (TDMAHf) and water by atomic layer deposition (ALD) on heated 4 Si wafers covered with native oxide in the temperature range from100 °C...
PublicationsOne-Shot phase-recovery using a Cellphone RGB Camera on a Jamin-Lebedeff Microscope
Jamin-Lebedeff (JL) polarization interference microscopy is a classical method for determining the change in the optical path of transparent tissues. Whilst a differential interference contrast (DIC) microscopy...
PublicationsLinear and nonlinear absorption of titanium dioxide films produced by plasma-ion assisted electron beam evaporation: Modelling and experiment
Titanium dioxide films have been prepared by plasma-ion assisted electron beam evaporation. Linear optical properties have been investigated in terms of spectrophotometry while using the beta-distributed...
PublicationsModified PCA and PLS: Towards a better classification in Raman spectroscopy–based biological applications
Raman spectra of biological samples often exhibit variations originating from changes of spectrometers, measurement conditions, and cultivation conditions. Such unwanted variations make a classification...
PublicationsMorpho-molecular ex vivo detection and grading of non-muscle-invasive bladder cancer using forward imaging probe based multimodal optical coherence tomography and Raman spectroscopy
Non-muscle-invasive bladder cancer affects millions of people worldwide, resulting in significant discomfort to the patient and potential death. Today, cystoscopy is the gold standard for bladder cancer...
PublicationsAnalysis method for detecting topological defect dark matter with a global magnetometer network
The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) is a network of time-synchronized, geographically separated, optically pumped atomic magnetometers that is being used to...
