FBG1000|Zhejiang GT Lasers Tech. Co., Ltd.

GT Lasers FBG1000 High power double-clad fiber grating pair, with chirped phase mask writing technology, through a set of high reflection (HR) and low reflection (LR) grating pairs to form a stable laser resonator, and output high power through OC coupler, low noise, low distortion laser. It can meet the specific needs of high power and high reliability of various fiber lasers.

◉ High efficiency, high reliability

◉ Extremely low temperature rise for high power applications
◉ Excellent reflection and transmission spectral characteristics, which can increase the SBS threshold

◉ High power continuous fiber laser

◉ Pulsed fiber laser
