Tunable Wavelength Filter
 |
In soliton lasers, the temporal pulsewidth is determined by the spectral bandwidth. PriTel has pioneered the use of easily changeable, pre-aligned optical filters in our fiber lasers to achieve the optimum soliton pulse shapes. These Quick Change Filter Cartridges provide pulsewidths from 10 ps to 0.6 ps.
In response to customer requests, PriTel has designed an external module for the Quick Change Filter Cartridge that functions as a tunable filter. These modules feature ease of operation, wavelength calibration and quick changes of the filters. The module accepts Quick Change Filter Cartridges with bandpass widths from 10 nm to 1 nm. With an insertion loss < 0.6 dB and no alignment required, the fiber-pigtailed Tunable Filter Module combines high performance with flexibility and ease of use. The Tunable Filter Module has been used with high satisfaction in scanning supercontinuum pulses. The modules are available with standard fiber or polarization maintaining fiber pigtails and with a variety of optical connectors.
