DFB & DFB-QCL Laser Diodes

Single Mode Pump Laser Diodes


Nano-Giga offers wide range of pump laser products with outstanding characteristics and reliability. Fitel is known as the market-leading brand for 1480/14xx-nm pump laser modules that has 400mW operating power. For Raman application, various wavelength that covers S-,C- and L-band can be selected. Furukawa also offers 980nm pump lasers with very high power up to 450mW operating. Polarization maintaining fiber(PMF) pigtail is implemented to achieve excellent stability of output power and spectrum. All PMF type is available for fiber laser or frequency doubling applications.

EM4's range of near infra-red fiber coupled pump lasers are designed for the harsh environments associated with defense, industrial and telecommunication applications. We have an excellent track record of supporting fiber telecoms, fiber lasers, fiber amplifiers, fiber optic sensing and free space communications.

Our product range includes high power diode lasers at 97x nm, 980 nm and 1060 nm. These are suitable for pumping Erbium (Eb) Doped Fiber Amplifiers (EDFA's) and Ytterbium (Yb) fiber amplifiers (YDFA's). These single mode diode lasers are also excellent pumps for femto-second fiber lasers.

DFB-QCL Diodes

    Single mode quantum cascade lasers in the MID-IR   

Quantum Cascade lasers are able to reach very high power emission over the entire
mid- and far-infrared spectrum, but as of today, they are still characterized by low efficiency when compared with currently available laser diodes operating in the near-IR. Quantum cascade (QCL) lasers are innovative coherent light sources in the mid-infrared wavelength region. This wavelength range is of particular importance for:


  Gas sensing
 • Liquid phase sensing
 • Tera Hertz generation
 • Spectroscopy applications.

DFB Lasers and Modules

EM4 designs, develops and manufactures state-of-the-art, ruggedized, optoelectronic components and packages  for the Defense, Aerospace, Life Science, CATV, Telecommunication and Industrial markets. EM4 is part of a global group of specialized optical companies that form Gooch & Housego.

Nano-Giga offers distributed feedback lasers (DFB lasers) simultaneously provide smooth, tunable control of wavelength and the extremely narrow spectral width required for precise fiber optic communication and spectroscopy applications. Integrated modules provide further narrowing of the spectral line in a compact OEM package that features simple tuning interface. G&H offers a broad range of DFB lasers in the C-band and L-band on 50 or 100 GHz channel spacing as well as at 1310 nm and 1064 nm. Power level options include 40-100 mW out of the fiber for high power 14-pin lasers and 10-18 mW options for high bandwidth 7-pin configurations.
