Abstract

We measured spectroscopic and laser action properties of a novel 8-position substituted pyrromethene-BF2, namely 1,3,5,7-tetramethyl-2,6-diethyl-8-n-propyl pyrromethene-BF2 complex. The laser action was performed with the corresponding dye solution in ethanol, which was placed in a Littman-type laser cavity pumped by the second harmonic of a Q-switched Nd:YAG laser. The spectroscopic measurements clearly indicated that the corresponding dye solution in ethanol exhibited intense absorption in the visible spectral region with large fluorescence quantum yield. It possesses rather low triplet–triplet absorption in the spectral region 460–550 nm and almost negligible triplet-triplet absorption in the lasing spectral region. As a consequence, it lases nearly as efficiently as commercially available benchmark laser dyes such as Rhodamine-6G and outperformed them in wavelength tunability in our laser cavity and pump geometry.

Experimental setup for the dye-laser system. The laser cavity was arranged as a typical Littman type. M1, M2, M3, mirrors; BS, beam splitter; L1, L2, L4, lenses; L3, cylindrical lens (f=5 cm); PD1, PD2, PD3, photodiode detectors. L1 and L2 formed a telescope to expand the pump laser beam with a magnification of 4:1. Cylindrical lens L3 focused the expanded pump laser beam on the dye cell to get a gain length of about 1 cm.

Wavelength-tuning curve of the PM-3. In the data acquisition, measurements were taken 100 times at each wavelength and averaged. The resulting wavelength-tuning curve was then smoothed by ten data points of adjacent averaging.

Laser slope efficiency of PM-3 versus Rh6G. The PM-3 and Rh6G are dissolved in pure ethanol at concentrations of 3.1×10-3 M and 2.0×10-3 M, respectively. In the data acquisition, measurements were taken 100 times at each wavelength and averaged. The laser output energies are measured at the wavelengths corresponding to maximum gain, that is, at 575 and 578 nm for PM-3 and Rh6G, respectively.
