1654nm pigtailed VCSEL laser test CH4

Idealphotonics' new 1654nm VCSEL laser uses the newly invented high contrast grating layer (HCG). HCG is about 50 times thinner than the traditional distributed Bragg reflector (DBR), but has higher reflectivity and wider spectral width. Our laser has a tuning range of up to 8nm and a tuning frequency of up to 100kHz, making it an ideal choice for testing CH4 gas.

Product features：TO-56 package, 7Pin、 Single-mode fiber, FC/APC connector、 With TEC, temperature stable、 CW continuous output power、 Single-mode VCSEL (~1654nm) fast wavelength tuning、 Built-in optical isolator, isolation ratio>20dB

Application area：Optical gas sensing (CH4)、 Ranging、 Optical time domain reflectometer、 Optical communication system (U band)
