![]() ![]() The technique is used for offset locking the frequency of a Ti:Sapphire laser used for laser cooling and trapping of calcium. They consist of a cathode made from the element of interest, an anode and an inert filler gas contained in a glass envelope. The sensitivity of the technique is sufficient to observe clear signals from isotopes of calcium unresolved by the inhomogeneous broadening and with natural abundances of less than 0.2%. Hollow cathode lamps (HCL) are discharge lamps designed for use in Atomic Absorption (AA) instruments. They are used to saturate the atomic transition in the low-density vapour of the lamp. One of the beams is frequency shifted by the modulator allowing for a variable frequency offset of the resulting signal. ![]() We report on a technique for obtaining dispersive saturated absorption features by two pump beams derived from an acousto-optic modulator.

Cathode materials and geometry achieve a combination of spectral purity and a suitable sputtering rate.Long running life and a 5 year shelf life.Rapid warm up to produce stable long term light emission.Calcium has a sharp, intense, analytical emission line at 422.7 nm. We offer a wide range of single-element and multi-element HCLs, which are ideal for determining most elements. A hollow cathode lamp with the cathode made of the material to be analyzed is used. Every genuine PerkinElmer lamp is designed for use with and tested on our spectrometers to assure compatibility and the highest performance. Minimal spectral interference from continuum emission, present in the cathode. Single Element Lumina Hollow Cathode Lamp (HCL) for the detection of elemental Cadmium (Cd).Narrow line width, for maximum sensitivity and linearity.Intense emission of resonance (ground state derived) lines.Hollow cathode lamps produced by Photron are designed and manufactured to achieve all of the following fundamental requirements for a spectral line source. Photron's P600 & P6 Multi Element HCLs: Perkin Elmer (51mm or 2").Photron's P500 & P5 Multi Element HCLs: All AAS systems (37mm or 1.5").For calcium and magnesium calibration, mix 100 mL of standard with 10 mL. Perkin Elmer (4 Pin Coded) - P600LL / P6-0000LL / P970LL Series Turn on instru- ment, apply to the hollow cathode lamp the current suggested. Perkin Elmer (9 Pin Coded) - P600 / P6-0000 / P970 series Select models with single element lamps and multi elements are available. Operating without noise, the hollow cathode lamps feature hermetically sealed glass that fills cleanly with gas.
