Description:

633nm,830nm,1064nm narrowband laser features embedded fiber can protect fiber well  from breaking, high reliability, and narrow band width. ATR20203 operates at a single 5V power supply, and outputs a 600 mW laser power. When laser works for Raman spectrometer, it's used to obtain high spectral stability and high resolution as a result. Being controlled through the TTL interface of pin-out and the communication protocol. Laser output power can be changed continuously by changing the LD working current with the command.

Features:

• Max output power: 500 mW
• Center wavelength: 633±0.5 nm,1064±0.5 nm,830±0.5 nm
• Line width (FWHM): < 0.1 nm
• Fiber: 105/125μm, 0.22NA, FC/PC
• Interface: UART
• Power supply: +5V/DC

Advantage:

• Narrow line
• High stability               
• Low power consumption               
• High reliability

Application:

• Raman System
• Biomedical
• Sensing
