CW-760-840810 nm near-infrared CW laser

810 nm

The CW-760-840 is a 810 nm continuous-wave Ti:sapphire laser. An optical pump excites titanium ions in a sapphire crystal. Their broad gain spectrum allows the resonator to select and tune the output wavelength within the specified range. Tuning changes the selected output wavelength so spectral features can be scanned with the same source. The tuning band specifies which lines can be reached; linewidth describes the width of the selected line.
