Use of Single-Frequency DPSS Lasers in Raman
Whilst diode lasers have advantages in terms of cost and efficiency, they are inherently limited in line-width narrowness and spectral purity. It’s particularly true for shorter wavelengths as it makes them unsuitable when high resolution is needed. DPSS lasers offer significantly narrower line-widths and spectral purity, and are worth their extra cost. UniKLasers specialise in making mid to high-power CW DPSS lasers with excellent line-width, spectral purity, and long-term stability across the spectrum, including such rare wavelengths as 523, 640, 689, 698, 780.24 nm, and others.
