Broadsweeper BS840 is a widely tunable external cavity laser based on a broadband SOA in a 840-nm band. Fast and narrow-band Acousto-Optic Tunable Filter (AOTF) is used as a selective intracavity element for tuning and sweeping the laser wavelength. Active temperature control of AOTF ensures excellent stability of the wavelength.
The following operation modes are available on the standard version:
- Operation at any selected wavelength within the full tuning range.
- Alternation between the two desired wavelengths (any two wavelengths from the full tuning range may be chosen).
- Linear sweep of wavelength with a rate of 200 Hz over the full tuning range (50 nm), and of 1 kHz over any 10-nm interval within the full tuning range.
Broadsweeper's external cavity is based on a PM-fiber. The standard version is shipped with FC/APC-terminated SM-fiber cable for connection to the optical adapter on the front panel. Output power is measured at the end of this cable. PM-PANDA-fiber cable with main polarization aligned to the key of the connector is optionally available upon request.
The instrument can be used for a large variety of applications including:
- optical coherence tomography
- spectroscopy
- optical metrology
Features:
- 3-mW output power ex fiber.
- 50-nm tuning range.
- Instantaneous linewidth of less than 0.05 nm.
- 200-Hz sweep rate over 50 nm.
- 1-kHz sweep rate over 10 nm.
- 1-kHz wavelength alternation rate for any two wavelengths within full tuning range.
- PM- or SM-fiber output.
- Powered directly from a wall outlet.
- RS-232 remote control.
