The Dartmouth miniature grating-based free-electron laser is a benchtop device producing coherent, tunable terahertz radiation. Two resonator designs, the planar grating horn and the grating horn are described and their performance compared with the simple planar grating case. The grating horn increases output intensity by a factor of 100 without limiting the tuning range of the device.

    Compact diode end-pumped acousto-optically Q-switched Nd:YLF laser was developed. As in effective CW diode end-pumped lasers, pump beam was made sufficiently narrower than resonator Gaussian mode to increase efficiency in Q-switched operation. The dramatic changes of output radiation structure...
