In partnership with APE, High Q Laser has introduced the picoEmerald, a turnkey, single-box, solid-state laser-based light source for coherent anti-Stokes Raman scattering (CARS) microscopy.

The product provides two tunable ultrafast-laser pulse trains from a single beam exit. It supplies three fully-automated, temporally and spatially overlapping, ultrafast pulse trains: 1,064nm out of the laser oscillator itself, from 690 to 990nm (signal range) and 1,150 to 2,300nm (idler range) from the OPO, respectively. The controller inside the OPO takes care of the power stability and wavelength tuning; the pump and Stokes beams are tailored to be sent into the microscope. The microscope user needs only to decide which mode to work in: signal and idler or signal and 1,064nm, and how much laser power to be applied.
