Patent ID: 8786840

Claim:
A device for remote optical detection comprising: a. one or more optical pumping sources, one or more lasers; and an optical response analyzer; b. each pumping source from said one or more optical pumping sources creating a pumping energy; c. said one or more lasers each comprising: i. a high reflectivity mirror, a laser media, an output coupler, and an output lens; ii. said laser media made of a material that emits a lasing power when exposed to said pumping energy; iii. said lasing power having a peak power greater than the peak power of said pumping energy; iv. said high reflectivity mirror reflective to said lasing power and transmissive to said pumping energy; v. said laser media optically connected to and positioned between said high reflectivity mirror and said output coupler along a pumping axis; and vi. said output lens optically connected to said output coupler and a sample area; d. each said high reflectivity mirror optically connected to an optical pumping source from said one or more optical pumping sources via an optical connection comprising one or more first optical fibers; and e. said sample area optically connected to said optical response analyzer; and f. further comprising at least one laser further comprising: i. a first lens, a first mirror, a second lens, a second mirror, a third lens, a third mirror, and a fourth mirror; ii. said first mirror optically connected to and positioned between said first lens and said second lens along said pumping axis; iii. said high reflectivity mirror, said Q-switch, said laser media, said optical coupler, and said output lens positioned between said second lens and said second mirror along said pumping axis; iv. said second mirror optically connected to and positioned between said output lens and said third lens along said pumping axis; v. said third lens optically connected to said second mirror and said sample area along said pumping axis; vi. said third mirror optically connected to said second mirror; vii. said third mirror optically connected to said fourth mirror; and viii. said fourth mirror optically connected to said first mirror; and g. whereby: i. said sample area is optically connected to said optical response analyzer through an optical path comprising at least part of said one or more first optical fibers; and ii. said optical response analyzer receives and analyzes optical responses from said sample area.
