20070046934, Mar 1, 2007

Filed:

Aug 26, 2005

Appl. No.:

11/213057

Inventors:

John Roy - Del Mar CA, US

Assignee:

New Wave Research, Inc. - Fremont CA

International Classification:

G01J 3/30

US Classification:

356318000, 356072000

Abstract:

A system is described that combines an optical spectrometer and a particle analysis spectrometer for simultaneous and/or sequential analysis of a sample placed in a sample chamber. A laser resonator generates a light beam on the sample in the sample chamber to produce a plasma formation and an aerosol formation. The optical spectrometer (spectrophotometer) analyzes a plasma formation generated from the sample surface of the sample, qualifies and/or quantifies and records chemical data of the sample. The particle analysis spectrometer analyzes an aerosol formation generated from the sample in the sample chamber, and qualifies and/or quantifies and records data of the sample. The combination of the optical spectrometer and the particle analysis spectrometer in the system enables simultaneous and/or sequential analysis, qualification and/or quantification, and recording of the chemical and physical data derived from the transfer of laser energy into a solid, liquid or gas.

Abstract:

Disclosed are apparatuses, systems, methods, and computer program products for monitoring the health of a laser such as solid-state laser or a gas laser. For example, the laser may be included in a laser machining system. The laser may be controlled by controller and an interface to communicate with the laser including status information and commands. The laser health monitor passively receives the status information from the laser and the commands to the laser without disturbing the communication between the laser and the laser controller. The laser health monitor generates alerts when one or more rules applied to the laser status information indicate a condition such as stale gas, low energy production, incorrect voltages, as well as other conditions. The alerts may be sent via email or SMS message or another communication mechanism to a recipient.
