Synchronised dual amplifier ultrafast laser system

1. Synchronised dual amplifier ultrafast laser system

A dual amplified laser system is required to seamlessly track photochemical and photobiological induced dynamics spanning 100s fs to 1 millisecond. The technical requirements of the laser must meet all the following specifications:

• The two amplifiers must be pumped by solid-state Ytterbium-based lasers for high stability and superior performance
• The footprint of the synchronised dual amplifier and common seed oscillator must be no greater than 1 m^2
• The maximum pulse energy from each amplifier must be 200 microJ at 50 kHz
• The pulse energy from each amplifier must be 100 microJ at 100 kHz
• The pulse-to-pulse energy stability must be < 0.5% RMS
• The beam quality (as defined by M^2) must be better than 1.2
• The repetition rate of each amplifier must be tuneable with an integrated pulse picker from single shot to 200 kHz
• The two amplifiers must be seeded by a single common oscillator operating at 80 MHz
• Using the common oscillator there must be an easily controlled delay in discrete steps of 12.5 ns between the two amplifier outputs between zero delay and 10 microseconds.
• The pulse pickers integrated into the two amplifiers must be used independently. For example, this would allow one amplifier to run at 100 kHz and the other at 50 kHz.

It is essential for the supplier to be able to demonstrate the laser system offered is fully established with references to numerous examples, operating in the field, evidenced by peer reviewed publications from different academic research groups using the offered laser system.
