Embodiment Construction

[0038] Although the invention has been described and explained with reference to several different embodiments of the invention, those skilled in the art will realize that the invention can be implemented in various ways without departing from the scope of the technical teaching as defined in the appended claims. Various changes in form and detail are made.

[0039] In its broadest sense, the present invention relates to mass spectrometers with pulsed or continuous emission laser systems that typically first generate a primary beam in a high performance laser crystal. At least some of the primary photons of this beam (which may also maintain a certain proportion of the original or primary energy) are then subjected to one or more frequency doubling stages in a suitable multiplier crystal in the multiplier system, whereby at least some of the primary photons are Part of it is the starting material, gradually forming photons with higher and higher energies.

Abstract

The invention relates to mass spectrometers with optically pumped lasers, whose laser light can be used for ionization by laser desorption, for the fragmentation of ions by photodissociation (PD), forthe initiation of ion reactions, and for other purposes. The invention provides a laser system for a mass spectrometer, with which at least two laser beams of different wavelengths can be generated for use at different points along an ion path from an ion source to an ion detector in the mass spectrometer.

Description

technical field [0001] The present invention relates to a mass spectrometer with a pulsed or continuous emitting laser, the laser of which can be used for ionization by laser desorption, for ion fragmentation by photodissociation (PD), for initiating ion reactions, and other purposes. [0002] The present invention provides a laser system for a mass spectrometer, by means of which at least two laser beams of different wavelengths (or frequencies) can be generated in pulsed form or continuously and along the ions from the ion source to the ion detector. Paths guide the laser beam to different points in the mass spectrometer. Background technique [0003] The prior art is explained below with reference to specific aspects. However, this should not be construed as limiting. Other useful developments and modifications known from the prior art beyond the relatively narrow scope of this introduction may also be used and will be readily apparent to those skilled in the art upon ...
