Fabrication of ultramicroelectrodes using a "teflon-like" coating material.
A new method was developed for the preparation of ultramicroelectrodes (UMEs). In this method, a photo-curable fluorinated functionalized perfluoropolyether, a liquid v-like polymer at room temperature, is used as the material for the insulation of metal microwires or carbon fibers. The UMEs prepared by this method were usually conical shaped and could be used both in aqueous solutions and with...
متن کاملUltrashort-pulse laser with an intracavity phase shaping element.
A novel ultrashort-pulse laser cavity configuration that incorporates an intracavity deformable mirror as a phase control element is reported. A user-defined spectral phase relation of 0.7 radians relative shift could be produced at around 1035 nm. Phase shaping as well as pulse duration optimization was achieved via a computer-controlled feedback loop.

Introduction Absorption spectroscopy is one of the oldest scientific methods for studying atomic and molecular structure. It is also one of the most powerful research tools for providing information about the world around us. One important application is ultrasensitive trace gas analysis, which is used in many area...
متن کاملUnidirectional hybrid silicon ring laser with an intracavity S-bend.
We demonstrate a hybrid silicon ring laser with an internal amplifying S-bend that couples a fraction of the counter-clockwise circulating light into the the clockwise direction. The device supported single-mode, unidirectional laser oscillation at certain bias conditions. A spatial field distribution model is derived to describe the unidirectional operation. A unidirectional clockwise laser ou...
متن کاملIntracavity measurement of liquid crystal layer thickness by wavelength tuning of an external cavity laser diode.
The gap of a planar-aligned liquid crystal (LC) cell is measured by a novel method: Monitoring the change in output wavelength of an external-cavity diode laser by varying the voltage driving the LC cell placed in the laser cavity. This method is particularly suitable for measurement of LC cells of small phase retardation. Measurement errors of +/-0.5 % and +/-0.6 % for 9.6-microm and 4.25-micr...
