For applications to intracavity laser absorption spectroscopy, we study the spectral properties of a multimode Tm3+-doped silica fibre laser pumped by a diode laser.
As the monolith is silica-based, this pump can be used for a variety of fluids, especially for organic solvents, such as acetonitrile and methanol, without swelling and shrinking problems.
With the aid of this technique, I investigated a collection of micrographs showing the optical discharge and the voids that remained after quenching to determining the periodic void formation mechanism in a single mode silica glass fiber pumped at 1480 nm [3], [4], [5].
Using silica fume enhanced the pumping performance, and particularly the pumping performance showed twice as much improvements when using zirconia silica fume compared to using regular silica fume.
Specifically, the 2.1 μm output from a Ho3+-doped silica fibre laser that is pumped with 1.15 μm first Stokes radiation is calculated with the use of a relatively simple numerical model.
Then, 1 mL 70 % ethanol was added to the lysate and, after mixing, the whole mixture was pumped over a silica membrane in the extraction chamber.
We have designed a simple human breath analysis system with this sensor, gas pump and dehumidifier of silica gel.
Because the pump was fabricated using silica wafers and standard photolithographic technologies, it can be conveniently integrated with other microfabricated functional devices for developing practical LOC devices.
To improve the output beam stability of a TEM00-mode solar-pumped laser, a twisted fused silica light-guide was used to achieve uniform pumping along a 3 mm diameter and 50 mm length Nd YAG rod.
The metabolic chamber was connected to the FoxBox with airtight tubes and air which was dried with silica gel prior to analysis, was pumped through the system (pull mode).
