Photop Technologies has released its Narrow Linewidth Laser (NLL) for Raman spectroscopy applications, the latest addition to its range of laser products.
Photop's NLL series lasers feature a reduced spectral bandwidth, which, the company says, is the key factor making the laser suitable for Raman Spectroscopy applications. A built-in temperature controller maintains the laser's temperature and results in power stability with variation less than ±2 per cent over sustained operating periods. The NLL series is available in at wavelengths of 532nm, 785nm and 1064nm, either multi-mode fibre-coupled or free space. The company can also provide customised fibres.
