Single output port

PicoEmerald's infrared pump light, signal light, and idler light are output from a single output port, overlapping in time and space, eliminating the need for additional optical paths to direct light of different wavelengths into the same location. For many applications, pump light, signal light, and idler light need to be used simultaneously. In applications such as coherent Raman scattering, different wavelength beams need to overlap in time and space. For multi output optical systems, adjusting the external light path of different wavelengths is more complex and not as convenient and fast as picoEmerald. PicoEmerald contains optical delay components. In order to eliminate the dispersion differences of optical devices on different wavelengths, the delay between infrared pump light and signal light can be adjusted to achieve spatial and temporal overlap of different wavelengths at the output port. Even the dispersion of the external optical path can be taken into account to achieve spatial and temporal overlap of different wavelengths at designated positions on the external optical path.

reliability

All optical modules in picoEmerald have undergone unit optimization analysis and mechanical stability calibration to ensure the mechanical stability of the system. In addition, the internal dynamic cavity control mechanism ensures that the picosecond pumped resonant cavity and the back-end OPO cavity work at high-quality efficiency positions. Built in cooling system ensures long-term stable operation of the light source. The light source is connected to a laptop with pre installed software through a communication interface, making it easy to perform all operations through the software.

Narrow linewidth picosecond pulse

PicoEmerald can efficiently generate 2ps narrow linewidth pulses because most vibrational energy levels only affect spectra within a few wavenumber ranges. Therefore, compared to femtosecond pulses, narrow linewidth picosecond pulses are more advantageous for experiments related to resonance specificity and vibration excitation, making them an ideal choice for microscope related applications. If a narrower linewidth is required, it can be combined with APE's pulse Slicer spectral clipper.
