Laser Applications to Chemical, Security and Environmental Analysis.
A compact fiber coupled laser induced breakdown spectroscopy (LIBS) sensor is presented. The detection of hazardous materials, e.g. explosives and land mines are promising applications of such a system.

An Yb fiber amplifier is seeded by a Cr4+Nd3+:YAG microchip laser. Due to improvement of the slope efficiency and suppression of ASE a pulsed diode laser is used as pump source of the active fiber.

A fiber coupled LIBS system is used for detection of mines and explosives. Laser excitation at 1.5 mum is preferred to generate LIBS signals using an Er:glass microchip laser as seed laser for an Yb:Er fiber amplifier.

A passively Q-switched Cr/sup 4+/:Nd/sup 3+/:YAG microchiplaser is amplified in an Yb-fiber. The occurring sidemodes are used for THz-generation in a DAST crystal. These first investigations show quasi cw output powers in the order of 0.2 nW.
