Schematic of the system setup. The 1150 LP filter is used to block the residual visible light from the NOPA. The 2-prism compressor is used to obtain short pulses out of the objective lens for 1300 nm excitation. NOPA, noncollinear optical amplifier; LP, long pass; M, mirror; MM, motorized mirror; IR, infrared; PMT, photomultiplier tube.
