We examine the behavior of two microlensed diode lasers at 413 and 661 nm placed in both free-running and extended cavity geometries. The 25 mW free-running 413 nm diode shows current tuning over 40 GHz and the 50 mW, 661 nm diode shows tuning of 55 GHz. In extended cavity the 413 nm diode coarsely tunes 5 nm and finely tunes 6 GHz, with a linewidth of 4 MHz. The 661 nm diode coarsely tunes 11 nm with fine tuning of 6 GHz. Beam profile ratios for the 413 and 661 nm microlensed diodes are 1:1.06 and 1:1.10 respectively. (C) 2004 American Institute of Physics.
