Communications 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 ...

Scientific 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 ...

Contrasting the beam interaction characteristics of selected lasers with a partially stabilised zirconia (PSZ) bio-ceramic [PDF]
, 2002 Differences in the beam interaction characteristics of a CO2 laser, a Nd:YAG laser, a high power diode laser (HPDL) and an excimer laser with a partially stabilised zirconia (PSZ) bio-ceramic have been studied.

Annales 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 ...

Effects of laser fluence on silicon modification by four-beam laser interference [PDF]
, 2015 This paper discusses the effects of laser fluence on silicon modification by four-beam laser interference. In this work, four-beam laser interference was used to pattern single crystal silicon wafers for the fabrication of surface structures, and the ...

Laser and electron deflection from transverse asymmetries in laser-plasma accelerators. [PDF]
, 2019 We report on the deflection of laser pulses and accelerated electrons in a laser-plasma accelerator (LPA) by the effects of laser pulse front tilt and transverse density gradients.

Indian 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 ...

Longitudinal Laser Shaping in Laser Wakefield Accelerators [PDF]
, 2000 We study the energetics of wake excitation during the laser-plasma interaction in application to laser wakefield accelerators. We find that both the wake amplitude and the accelerating efficiency (transformer ratio) can be maximized by properly shaping ...

Towards redistribution laser cooling of molecular gases: Production of candidate molecules SrH by laser ablation [PDF]
, 2013 Laser cooling by collisional redistribution of radiation has been successfully applied in the past for cooling dense atomic gases. Here we report on progress of work aiming at the demonstration of redistribution laser cooling in a molecular gas.
