Claim:
1. A spectrometer for acquiring a Raman spectrum from a sample, the spectrometer comprising: a dual laser package including a first laser, a second laser and a mount located within an excitation source housing, wherein the first laser produces a first laser beam for generating a first Raman spectra from the sample, and the second laser produces a second laser beam for generating a second Raman spectra from the sample, wherein at least one of the first laser or the second laser each comprises a distributed Bragg reflector diode laser and the first laser is electrically coupled to a conductive first pad on the mount and the second laser is electrically coupled a conductive second pad on the mount, and the conductive first and second pads are electrically isolated from one another; a detector adapted to collect the first Raman spectra and the second Raman spectra; a processor that processes the collected first and second Raman spectra to provide the Raman spectrum, the first laser beam has a first wavelength; and the second laser beam has a second wavelength that is different than the first wavelength.
