APE picoEmerald FT

Best in class Coherent Raman light source that is as easy to use as a femtosecond two-photon excitation laser. 

Tuning speed: 1.5 s for a random tuning step, up to 100x faster than previous generation picoEmerald S. 

Highly improved signal-to-noise ratio mainly due to the reduction of the laser repetition rate leads to 10x faster image acquisition compared to picoEmerald S. Shot noise limited performance of the Pump beam (>5 MHz, 10 mW). 

In a single box, picoEmerald provides fully automated, temporally and spatially overlapping picosecond pulse trains: 1032 nm from the laser oscillator and the OPO Signal beam. Tuning now down to 210 cm^-1 to access low frequency vibrational bands.

Features :

• One-box, hands-free, shot noise limited
• Fast wavelength tuning (100x faster compared to previous model)
• Wavelength tuning speed: 1.5 s for a random tuning step
• Fully automated and computer controlled
• 2 ps pulses with 10 cm-1 spectral width
• Multi-Color, wavelength tunable outputs

                  * Signal wavelength: 660 nm … 1010 nm
                  * Fundamental: 1032 nm
                  * Idler wavelength (optional): 1055 nm … 2340 nm

• Temporal and spatial overlap of Signal and Fundamental beam (Pump and Stokes for CARS/SRS)
• 40 MHz pulse repetition rate
• Active and passive stabilisation, ideal for long-term experiments

Applications:

• Light source perfectly designed for CARS/SRS applications
• Integrated EOM (20 MHz modulation frequency)
• Shot noise limited ⇒ Extremely low noise compared to all-fibre laser systems
• Highly sensitive and fast imaging of: Raman tags, Fingerprint region, CH₂-CH₃
• 210 cm^-1 … 5450 cm^-1 energy difference (Pump to Stokes)
• Compatible with commercial microscopes and homebuilt setups
