Additional L-Band Power
High Power (30 mW) Version of Our Most Popular Model
Easy Operation

The ASE730 White Light Test Source is a low noise, high power C&L source that delivers more than +15 dBm of output power across the C&L Band wavelength. It is designed to perform well beyond the industry standard. Key features of all our ASE products include low intensity noise, broadband output, and exceptional wavelength stability. This ASE Source takes advantage of Erbium-doped fluoride fiber, pumped with a single 1480 nm laser diode, to produce 30 mW (15 dBm) of broadband "white light". This rare-earth fiber design allows for a higher degree of power and wavelength stability than conventional silica fibers with multiple pumping lasers. The output fiber is a standard SMF-28 silica fiber.

Thorlabs also offers a Single Mode Benchtop SLD Source that provides a minimum of 22 mW of output power in the 1535 - 1565 nm range. This alternative may be suitable for some C&L Band applications.

Response from Laurie at Thorlabs to jhawkins: Weve been in contact with the vendor for the ASE-FL7002, and unfortunately, they have no data or specs on the lifetime of these. However, they did comment that it should be long because they are designed for telecommunication use. You mentioned that you have several units that appear to have varying outputs. Do you mean that the output power varies from unit to unit or that the output power of a given unit varies per day. The former would be somewhat expected. There will be some variation in output power from unit to unit. The latter, particularly if it is drastic, would not be expected.

Please let me know what the life expectency of the light source is. i.e., is there an approximate number of hours after which the power would be noticeably reduced? We have several ASE-FL7002 units that appear to have varying power outputs. I look forward to your response. John
