Picosecond Laser Tunable The picosecond laser picoEmerald emits ultra-short pulses with a duration of 2 picoseconds (other durations possible). The wavelength tuning of the ps laser is fully automated across a tuning range of 700 to 990 nm (Signal) and 1080 to 1950 nm (Idler). The fundamental beam at 1032 nm is also available. A wavelength scan / sweep function for fast spectra acquisition over certain specific wavelengths is included. The key-facts of the picoEmerald are: • Wavelength 1 IR beam 1032 nm • Wavelength 2 tunable 700 … 990 nm • Wavelength 3 tunable 1080 … 1950 nm • Temporal and spatial overlap of the output wavelengths • Integrated time-delay between the wavelengths • A common output port for all beams • Fully automated wavelength tuning • EOM optionally integrated picoEmerald provides ultra-short picosecond laser pulses with a pulse repetition rate of 80 MHz. A picosecond laser version with a high-repetition rate of 320 MHz has already been demonstrated in a customer-specific setup. Faster Achievements with a Single Output Port With the picosecond laser picoEmerald, Idler and Signal beams and the IR beam (1 µm from the pump laser) are designed to come from one and the same output. They are perfectly overlapping in space and time. Therefore, there is no need for the user to use additional optics to guide the different beams into one location. Users often want to use the entire wavelength range provided by the IR beam and the Signal and Idler output. Some applications, such as Coherent Raman Spectroscopy, even require the different beams being spatially and temporally overlapped.
