The pioneering TESLA linear accelerator and free electron laser project is initially introduced. Elementary analysis of cavity resonator with signal and power considerations is presented. Two alternative simulation models of cavity control system are proposed.

We report on an ultralow-threshold Raman laser based on a CaF2 whispering-gallery-mode resonator. The laser is demonstrated to have a conversion efficiency above 60%. The observed low lasing threshold is made possible by the ultrahigh optical quality factor of the cavity, which is on the order of Q=1010. The laser is fibercompatible and is fabricated with a very simple technique. We also demons...

Lowest-order, single-mode laser oscillation is reported in gain-guided index-antiguided fiber lasers having core diameters from 100 to 400 microm. A model is presented explaining how to select resonator mirrors to assure single-mode operation.

Recently, a high efficiency, narrow-linewidth, chip-based stimulated Brillouin laser (SBL) was demonstrated using an ultra-high-Q, silica-on-silicon resonator. In this work, this novel laser is more fully characterized. The Schawlow Townes linewidth formula for Brillouin laser operation is derived and compared to linewidth data, and the fitting is used to measure the mechanical thermal quanta c...

MEMS oscillators are well-suited for filter and timing applications owing to high resonator quality factors. Active compensation of frequency variation in conventional commercial MEMS oscillators is limited by their tuning range, which is typically <1,000ppm. This paper demonstrates an extremely wide tuning range for oscillations of a silicon clamped-clamped beam via the optical spring effect. ...

The semiconductor laser (SCL) is the principal light source powering the worldwide optical fiber network. The ever-increasing demand for data is causing the network to migrate to phase-coherent modulation formats, which place strict requirements on the temporal coherence of the light source that no longer can be met by current SCLs. This failure can be traced directly to the canonical laser des...

The Q-switched Nd:YAG laser operating in a single axial mode with a Fourier-transform-limited bandwidth is a useful source for nonlinear and high-resolution spectroscopic studies. In the past, single-axial-mode operation of the Nd:YAG laser received considerable attention,' and single-mode operation of a TEMNoo-mode Q-switched oscillator has been reported.2'3 More recently, single-mode operatio...

In modern dentistry applications, two different types of laser occupy dominant positions: gas lasers and solid-state lasers. The first of these categories includes the Co2 laser (10 600 nm) and the argon laser (480 + 515 nm), while examples of the solid-state laser are the Nd:YAG (1064 nm), Er:YAG (2940 nm), Er:CrYSGG (2780 nm) and the diode laser (mainly 810 and 980 nm). As the name suggests, ...
