Towards fully commercial, UV-compatible fiber patch cords

Robust optical fiber patch-cords for in vivo optogenetic experiments in rats

In vivo optogenetic experiments commonly employ long lengths of optical fiber to connect the light source (commonly a laser) to the optical fiber implants in the brain. Commercially available patch cords are expensive and break easily. Researchers have developed methods to build these cables in house for in vivo experiments with rodents [1-4]. However, the half-life of those patch cords is grea...

Towards Compatible Triangulations

Compact, fiber-compatible, cascaded Raman laser.

Cascaded Raman Stokes lasing in an ultrahigh-Q silica microsphere resonator coupled to a tapered fiber is demonstrated and analyzed. With less than 900 microW of pump power near 980 nm, five cascaded Stokes lasing lines are generated. In addition, a threshold power of 56.4 microW for the first-order Stokes lasing is achieved. The Stokes lasing lines exhibit distinct characteristics depending on...

Towards Incentive-Compatible Reputation Management

Traditional centralized approaches to security are difficult to apply to large, distributed, multi-agent systems. Developing a notion of trust that is based on the reputation of agents can provide a softer notion of security that is sufficient for many MAS applications. However, designing a reliable and “trustworthy” reputation mechanism is not a trivial problem. In this paper, we address the i...

Caesium sputter ion source compatible with commercial SIMS instruments

A simple design for a caesium sputter cluster ion source compatible with commercially available secondary ion mass spectrometers is reported. This source has been tested with the Cameca IMS 4f instrument using the cluster Sin and Cun ions, and will shortly be retrofitted to the floating low energy ion gun (FLIG) of the type used on the Cameca 4500/4550 quadruple instruments. Our experiments wit...
