sts and observe the latest
work. For a list of the persistent lines of spark spectra, consult one of the CRC manuals (Handbook of
Chemistry and Physics). Even the old publications are quite accurate.

(Bacillus Thuringiensis)
Applications
The LIBS technique is useful in areas such as:
• Environmental monitoring (soil contamination, particulates)
• Materials analysis (metals, plastics)
• Forensics and biomedical studies (teeth, bones, glass)
• Military and safety applications (explosive particles, chemical and biological warfare agents)
• Art restoration/conservation (pigments, precious/ancient metals)
Laser Requirements for LIBS2000+
You can supply your own Q-switched laser (from our certified list), or you can purchase one through
Ocean Optics. We recommend the ULTRA CFR Nd:YAG laser from Big Sky Laser Technologies
(www.bigskylaser.com/compactseries.html). The ULTRA CFR was used when testing prototypes of the
LIBS2000+. The rugged and field-portable ULTRA CFR delivers Q-switched pulses at 1.06 µm, with
variable repetition rates from 1 to 20 Hz. At 1.06 µm, the laser has a pulse stability of ±3%.
