An inhibited laser [PDF]

open access: yesCommunications Physics, 2021
AbstractTraditional lasers function using resonant cavities, in which the round-trip optical path is equal to an integer multiple of the intracavity wavelengths to constructively enhance the spontaneous emission rate. Taking advantage of the cavity enhancement effect, the narrowest sub-10-mHz-linewidth laser and a 10−16-fractional-frequency-stability ...

Photosensitizers-Loaded Nanocarriers for Enhancement of Photodynamic Therapy in Melanoma Treatment

open access: yesPharmaceutics, 2023
Malignant melanoma poses a significant global health burden. It is the most aggressive and lethal form of skin cancer, attributed to various risk factors such as UV radiation exposure, genetic modifications, chemical carcinogens, immunosuppression, and ...

Efficient plasma electron accelerator driven by linearly chirped multi-10-TW laser pulses

open access: yesScientific Reports, 2023
The temporal rearrangement of the spectral components of an ultrafast and intense laser pulse, i.e., the chirp of the pulse, offers significant possibilities for controlling its interaction with matter and plasma. In the propagation of ultra-strong laser

Laser optomechanics [PDF]

open access: yesScientific Reports, 2015
AbstractCavity optomechanics explores the interaction between optical field and mechanical motion. So far, this interaction has relied on the detuning between a passive optical resonator and an external pump laser. Here, we report a new scheme with mutual coupling between a mechanical oscillator supporting the mirror of a laser and the optical field ...

Lasers [PDF]

open access: yesAnnales de Dermatologie et de Vénéréologie, 2012
Lasers are a very effective approach for treating many hyperpigmented lesions. They are the gold standard treatment for actinic lentigos and dermal hypermelanocytosis, such as Ota nevus. Becker nevus, hyperpigmented mosaicisms, and lentigines can also be successfully treated with lasers, but they could be less effective and relapses can be observed ...

Dual wavelength digital holography for 3D particle image velocimetry [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2015
A multi-exposure digital in-line hologram of a moving particle field is recorded by two different wavelengths and at different times. As a result, during the reconstruction step, each hologram can be independently and accurately reconstructed for each ...

Toward low-loss mid-infrared Ga2O3–BaO–GeO2 optical fibers

open access: yesScientific Reports, 2023
The development of efficient and compact photonic systems in support of mid-infrared integrated optics is currently facing several challenges. To date, most mid-infrared glass-based devices are employing fluoride or chalcogenide glasses (FCGs).

Hydroxyapatite Thin Films of Marine Origin as Sustainable Candidates for Dental Implants

open access: yesPharmaceutics, 2023
Novel biomaterials with promising bone regeneration potential, derived from rich, renewable, and cheap sources, are reported. Thus, thin films were synthesized from marine-derived (i.e., from fish bones and seashells) hydroxyapatite (MdHA) by pulsed ...

To laser or not?

open access: yesIndian Journal of Ophthalmology, 2018
A 64-year-old male patient presented to the clinic with diminished vision in his right eye for the past 2 years. Examination revealed a best-corrected visual acuity (BCVA) of counting fingers at 1 m with a scarred choroidal neovascular membrane (CNVM) in the right eye while the left eye had a BCVA of 20/20 with a small peripapillary subretinal ...
