Tuneable pulsed laser for applications in spectroscopy

Physical Review Applied, 17, 014041 DOI:

The tunable laser wavelength. (a)–(c) The normalized experimental emission spectra measured for three different applied voltages above the lasing threshold. (d) The position of the main emission peak versus the applied voltage. The first series (orange dots) and the second series (purple diamonds) are measured for pulse-energy densities of 2.34 J/cm2 and 3.21 J/cm2, respectively.
