Narrow Linewidth Laser (NLL)

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.
