| Abstract | |
We have built a spectral shaping system, based on a virtually imaged phased array (VIPA) and a digital micromirror device (DMD), to manipulate a multimode diode laser spectrum. Due to its working principles, the system reduces the available optical power by similar to -27 dB. To overcome this limitation, we have seeded its output, using a double-pass configuration, in a tapered amplifier, to increase the available power to similar to 60 mW. We have implemented spectral features with a resolution of 0.1 cm-1, which is limited by the characterization spectrometer. This may be attractive for a wide range of applications, especially for cooling the translational, vibrational, and rotational degrees of freedom of a diatomic molecule. (AU) | |
