The ground and low-lying excited states and feasibility of laser cooling for GaH+ and InH+ cations.

The potential energy curves and transition dipole moments of 12Σ+ and 12Π states of GaH+ and InH+ cations are performed by employing ab initio calculations. Based on the potential energy curves, the rotational and vibrational energy levels of the two states are obtained by solving the Schrödinger equation of nuclear movement. The spectroscopic parameters are deduced with the obtained rovibrational energy levels. The spin-orbit coupling effect of the 2Π states for both the GaH+ and InH+ cations are also ...

Intensity noise behavior of an InAs/InGaAs quantum dot laser emitting on ground states and excited states.

We experimentally and numerically study the amplitude stability of an InAs/InGaAs quantum dot laser emitting simultaneously on ground states (GSs) and excited state (ESs) at center wavelengths of 1245 and 1168 nm, respectively. The stability is quantified by a spectrally resolved noise current analysis that is dependent on the laser injection current. We find a non-monotonic behavior of the amplitude noise which shows a reduction of up to 4 dB when the GS and ES emit simultaneously. Simulations based on a...

Understanding State Regulation of Biosimilars and Effect on Prescribers.

Biologics are a mainstay of treatment for many dermatologic conditions, however the high costs can be prohibitive for many patients. A growing market of biosimilar drugs is emerging with the hope of providing patients access to more affordable medications. While the FDA has created an abbreviated licensure pathway for these drugs, states are still in the process of creating regulations regarding their substitution for reference biologics. This article looks to raise awareness of the current federal regulati...

Relative intensity noise reduction in a dual-state quantum-dot laser by optical feedback.

We report a reduction of the relative intensity noise (RIN) in a dual-state emitting quantum-dot laser subject to the state-selective optical feedback on the ground state and excited state. Numerically, we map the evolution of the RIN for variations of the optical feedback phases for both states. We report important differences in the impact of the feedback when applied to the ground or excited state, and observe regimes for which a significant reduction in RIN is achieved. Experimentally, we confirm these ...

Laser-Induced Conversion of Teflon into Fluorinated Nanodiamonds or Fluorinated Graphene.

Laser-assisted materials fabrication is an advance that has propelled recent carbon synthesis approaches. Direct laser writing on polyimide or lignocellulose materials by a CO2 laser has successfully transformed the substrates into hierarchical graphene. However, formation of other carbon allotropes such as diamond and fullerene remains challenging. Here we report the direct synthesis of fluorinated nanodiamonds or fluorinated graphene by treating polytetrafluoroethylene (Teflon, or PTFE) with a 9.3 μm pul...

Standoff analysis of laser-produced plasmas using laser-induced fluorescence.

We report the use of laser-induced fluorescence (LIF) of laser ablation (LA) plumes for standoff applications. The standoff analysis of Al, as major and minor species in samples, is performed in a nanosecond laser-produced plasma created at a distance of ∼10  m. The LIF of LA plumes is carried out by resonantly exciting an Al transition at 394.4 nm (S2-P2) using a continuous wave (cw) tunable laser and by collecting the direct-line fluorescence signal at 396.15 nm. The spectral resolution of LIF is ...
