Key performance parameters when selecting a laser for Raman spectroscopy are: spectral linewidth, frequency stability, spectral purity, beam quality, output power and power stability. In addition, the compactness, robustness, reliability, lifetime and cost structure should be considered.
In the experimental quantum research community, widely tunable continuous-wave optical parametric oscillators (CW OPOs) are gaining recognition as novel sources of tunable laser light with great potential – not least due to their unprecedented wavelength coverage. Yet, the overall experimental requirements remain often challenging for the performance of turnkey OPO devices.
