Cr:Forsterite (Cr:Mg2SiO4) crystal is a new tunable laser material that fills the spectral void in the near-IR region. The tuning range covers the important spectral range from 1130 to 1348 nm, which provides a minimal dispersion in optical fibers. The Cr:Forsterite laser eventually explores its niche applications for semiconductor characterisation, eye-safe ranging, medical, industrial and scientific research. Both pulsed and continuous-wave (CW) laser operations have been obtained when pumped with 532, 578, 629 and 1064 nm.
