    Notes: The construction and single-mode tuning characteristics of a short-external-cavity (SXC) module for InGaAsP and AlGaAs semiconductor diode lasers are presented. The SXC system is a cost effective, simple, and rugged means to achieve single-mode tuning and complete spectral coverage over large spectral regions with normally multimode lasers. With AlGaAs lasers, complete spectral coverage in overlapping ∼5-cm−1 intervals over ∼400 cm−1 is obtained, while with InGaAsP diode lasers, complete spectral coverage in overlapping ∼5-cm−1 intervals of 100–200 cm−1 is obtained.

    Notes: Near infrared spectrum of the 3ν2 overtone band (ν2=3←0) of H+3 has been observed at 1.4 μm. The spectrum is weaker than the ν2 fundamental band by a factor of ∼250. High sensitivity plasma spectroscopy using velocity modulation and unidirectional multiple passing has enabled us to observe 15 rovibrational transitions. Short-external-cavity InGaAsP diodes were used as tunable near infrared radiation sources. The narrow tuning range and the availability of diodes limited the observation to a fraction of observable transitions. Nevertheless, the observed results provide information on the rovibrational energy of the 3ν2(l=1) state which may be used to further improve the variational calculations by Miller and Tennyson.
