RLM658RA Series Laser | |||
The 658nm Raman Laser Module is a highly integrated laser module with laser optics and electronics in a single package. It features fiber coupling option, very low optical noise and up to 20KHz TTL modulation. Laser output power can be remotely controlled through electrical cable connected to the back panel of the package. Lower laser temperature setting can improve laser diode operational lifetime. The unique designed electrical driver enable this Laser Module has the lowest power consumptions compare to the similar product in the industry. The 658nm Raman Laser Module utilize unique technology to stabilize laser wavelength and has a narrow spectrum width less than 0.1nm which made this laser an ideal laser source for all your Raman applications. |
