Claim 0:
1. A system for remote optical detection comprising:
an optical pumping source optically connected to an optical fiber;
a first lens optically connected to the optical pumping source and optical fiber;
an adjustable focus lens arrangement optically connected to at least one of the optical pumping source and the optical fiber;
a first mirror optically connected to the first lens and the adjustable focus lens arrangement;
a passively q-switched laser optically connected to the adjustable focus arrangement;
a beam expander optically connected to the passively q-switched laser;
a second mirror optically connected to the beam expander;
a sample area optically connected to at least the beam expander;
a second lens proximate the sample area and optically connected to the second mirror;
a third mirror positioned proximate the sample area and optically connected to at least the second mirror, whereby at least some optical response from the sample area is reflected to the third mirror; and
a spectral emission control optically connected to at least one of the optical fiber and the optical pumping source, wherein the spectral emission control comprises a first spectral emission control lens optically connected to the third mirror and a second spectral emission control lens optically connected to the first spectral emission control lens and the first mirror to reflect at least some optical response from the sample area, reflected by the second mirror to the third mirror, through the first and second spectral emission control lens towards the first lens, which is optically connected to the optical fiber.
