Abstract:
1. An optical nose system having a broadly tunable, narrow linewidth mid-IR laser source wherein the laser source has a modular structure and comprises a) a tunable seed laser unit including a single-longitudinal mode, widely tunable TM b) a pulsed pump laser unit including a single-frequency, high energy, Q-switch laser having a laser output; c) an Optical Parametric Generator-Amplifier, pumped by said pulsed pump laser unit and seeded by said seed tunable laser unit having a mid-IR output selectively variable over about 2 to 20 μm; and wherein said pulsed pump and seed tunable lasers are pumped by a single diode, diode array, or fiber laser.
