Quantum vacuum experiments using high intensity lasers

High Intensity Lasers in Periodontics: A Review

Background and Aim: Lasers can serve as a new powerful tool in dentistry. High intensity laser therapy is becoming the treatment of choice compared with conventional periodontal therapy due to accurate incision and soft and hard tissue ablation, hemostasis, reduction of postoperative pain and infection, optimal debridement, and enhanced healing. Although high intensity laser therapy assumes to ...

High - Intensity Short - Pulse Lasers

Intensity noise properties of quantum cascade lasers.

We present investigations of the the relative intensity noise (RIN) of a quantum cascade laser (QC) laser in continuous wave operation. We analyze the intensity noise properties in terms of the relative intensity noise (RIN). In contrast to conventional interband semiconductor diode lasers we obtain a different scaling behavior of RIN with increasing optical output power for QC lasers. From a s...

Modulation Response and Relative Intensity Noise Spectra in Quantum Cascade Lasers

Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper. The present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. Two equations were derived to calculate the noise and modulation response. Calcula...

High-intensity Lasers in Nuclear Science

Recent developments in high intensity lasers open up a new approach to investigating nuclear reactions in the laboratory without access to nuclear reactors or particle accelerators. By focusing the laser spot, very high laser intensities in excess of 10 W cm can now be produced. Under these conditions, matter in the focal spot is turned into hot dense relativistic plasma. The laser interactions...
