B. Golubovic et al., OPTICAL FREQUENCY-DOMAIN REFLECTOMETRY USING RAPID WAVELENGTH TUNING OF A CR4+FORSTERITE LASER, Optics letters, 22(22), 1997, pp. 1704-1706
We present a cw chromium-doped forsterite laser that permits rapid wav
elength tuning over a broad bandwidth and demonstrate the application
of this source to frequency-domain ranging and optical tomography. The
entire tuning range of 1200 to 1275 nm can be swept in less than 500
mu s. This permits frequency-domain ranging to be performed with a sca
n rate of 2 kHz and an axial resolution of 15 mu m. (C) 1997 Optical S
