Abstract

We describe a compact, narrow-linewidth, etalon-tuned titanium:sapphire laser cavity that is designed for field environmental sensing and is pumped by the second harmonic of a kilohertz Nd:YAG laser. The fundamental tunable range is from 690 to 1100 nm, depending on mirror reflectivities and the optics kit used. The conversion efficiency is at least 25% for the fundamental and 2–3% for intracavity frequency doubling from 3.5 to 4 W 532 nm pump power. The linewidth is <0.1 cm-1, and the pulse width is 18 ns. Applications of this cavity include the measurement of trace gas species by laser-induced fluorescence, cavity ringdown spectroscopy, and micropulse lidar in the UV–visible regions.

Ti:sapphire cavity configuration includes the output coupler (OC); end mirror (EM); birefringent filter (BF); Ti:sapphire rod (Ti:S); BBO doubling crystal (DC); isosceles prism (P); etalon (E); and stepper motor (SM). The cavity has an optical length of 20 cm and is enclosed in an aluminum housing to maintain constant pressure and temperature.

Linewidth of the fundamental output of the Ti:sapphire cavity at full width at half-maximum (FWHM) is 0.07 cm-1. The solid curve represents the Lorenztian fit.

Beam profile of 706 nm from a CCD camera at ∼2 m distance. The abscissa refers to the spatial index in arbitrary units (CCD pixels). The dots (stars) represent the profile of the major (minor) axis and the dash–dot (dash–dash) curve is its corresponding Gaussian fit.

Reference cell signal (top) and difference signal from the ambient sampling cell (bottom) during normal operation of the instrument when the etalon is alternately tuned on and off the absorption feature. The reference cell signal is a 1 s average; the ambient cell signal is a 2 min average difference signal. See text for details.
