Free Space 785nm Butterfly Laser Diode
DFB fiber coupled 785nm butterfly laser diode adopts advanced laser welding process to realize butterfly pigtail type package, built-in TEC cooler, compact structure and small size, They’ve been widely used in the field of optical fiber communication. Under the high-precision temperature control of TEC cooler, the advantages of high stability and wavelength locked, which widely used in the field of optical fiber sensors. At present, the basic use of 785nm butterfly laser diode is Raman spectrometers because they have narrow spectral line widths and high spectral center wavelength stability, the more concentrated energy, the greater the Raman effect will be.
