Laser noise in cavity-optomechanical cooling and thermometry

New Journal of Physics, 2013
We review and study the roles of quantum and classical fluctuations in recent cavity-optomechanical experiments which have now reached the quantum regime (mechanical phonon occupancy ≲1) using resolved sideband laser cooling.

Laser phase noise effects on the dynamics of optomechanical resonators

, 2010
We investigate theoretically the influence of laser phase noise on the cooling and heating of a generic cavity optomechanical system. We derive the back-action damping and heating rates and the mechanical frequency shift of the radiation pressure-driven ...

Magneto optical trapping of Barium

, 2008
First laser cooling and trapping of the heavy alkaline earth element barium has been achieved based on the strong 6s$^2$ $^1$S$_0$ - 6s6p $^1$P$_1$ transition for the main cooling.

Two-dimensional cooling without repump laser beams through ion motional heating

Communications Physics
Laser cooling typically requires one or more repump lasers to clear dark states, which complicates experimental setups, especially for systems with multiple repumping frequencies.

A Quantum Heat Exchanger for Nanotechnology

Entropy, 2020
In this paper, we design a quantum heat exchanger which converts heat into light on relatively short quantum optical time scales. Our scheme takes advantage of heat transfer as well as collective cavity-mediated laser cooling of an atomic gas inside a ...

Doppler-free frequency modulation spectroscopy of atomic erbium in a hollow cathode discharge cell

, 2011
The erbium atomic system is a promising candidate for an atomic Bose-Einstein condensate of atoms with a non-vanishing orbital angular momentum ($L \neq 0$) of the electronic ground state.

Longitudinal and transverse cooling of relativistic electron beams in intense laser pulses

New Journal of Physics, 2015
With the emergence in the next few years of a new breed of high power laser facilities, it is becoming increasingly important to understand how interacting with intense laser pulses affects the bulk properties of a relativistic electron beam.

Relevant parameters for laser surgery of soft tissue

Scientific Reports
In recent years, the laser has become an important tool in hospitals. Laser surgery in particular has many advantages. However, there is still a lack of the understanding of the influence of the relevant parameters for laser surgery.

Enhanced Optical Cooling of Ion Beams for LHC

, 2006
The possibility of the enhanced optical cooling (EOC) of Lead ions in LHC is investigated. Non-exponential feature of cooling and requirements to the ring lattice, optical and laser systems are discussed.
