Problem Statement
NRC’s Security and Disruptive Technologies (SDT) research center hosts research in the field of strong optical interactions with materials and nanostructures, with applications towards improved sensing. High-intensity femtosecond lasers are required to reach the high-field regime of light-solid interaction. Because NRC utilizes materials with widely different properties and with various length scales (nanoscopic to macroscopic), the laser system must efficiently deliver a unique combination of intense and weak fields over a wide spectral range, from deep-ultraviolet to mid-infrared frequencies, at high repetition rate (100 kHz), and with short pulses. The high repetition rate assures the high-field response of small nano- and atomic-scale materials can be adequately measured; the wide spectral coverage enables pumping and probing of material-specific resonances.
In this challenge, NRC is seeking a femtosecond laser system that operates at a repetition rate of 100 kHz and that, starting from a pump laser with a center wavelength of 1.03 μm and pulse duration of 200 femtoseconds (fs), delivers a minimum of three laser outputs with pulse durations
Desired outcomes and considerations
Essential (mandatory) Outcomes
The solution must:
1. Be compatible with a femtosecond Yb pump laser (LightConversion Carbide CB3) operating at 100 kHz repetition rate, with a center wavelength of 1.03 μm, and with pulse duration of 200 femtoseconds and average power of up to 80W.
2. Output (O1) mid-infrared femtosecond pulses with a wavelength tunable between 2.5 – 10 µm (potentially with a gap between 4 – 4.3 µm), pulse duration less than 100 femtoseconds, and pulse energy of at least 2 μJ, throughout the wavelength range. Wavelengths longer than 4 µm must be Carrier-Envelope-Phase (CEP) stable (passive).
3. Output (O2) near-infrared femtosecond pulses with 10 femtoseconds duration or shorter, at 1.03 µm wavelength, with at least 3 W of power.
4. Output (O3) visible and ultraviolet femtosecond pulses with a wavelength tunable between 450 – 600 nm and pulse duration less than 70 femtoseconds.
5. Have all these outputs available simultaneously.
6. If cooling is required, water-to-air heat exchangers (chillers) must be provided.
7. Operate in laser lab with a temperature of 20°C+/-3°C and 35 % humidity.
8. Occupy no more than 0.6 m x 4 m of table space.
9. Be completely enclosed in appropriate laser-safety containers.
Additional Outcomes
The solution should:
1. Have additional integrated diagnostics, displayed by an integrated software, such as :
near-infrared cameras and photodiodes to monitor alignment and power of the pump beams.
near-infrared (
mid-infrared beam profiler covering 2 – 16 µm wavelengths.
mid-infrared spectrometer, covering at least 2 – 10 µm wavelengths, operating at least at 1 Hz (1spectrum/second).
Visible-ultraviolet spectrometer to monitor output O3.
Pulse measurement device (autocorrelator, FROG, …)
2. Allow software selection of the wavelengths of the tunable outputs.
3. Extend the wavelength range of output (O3) to below 450 nm, and between 600 – 850 nm.
4. Provide one additional output (O4) of 35 femtoseconds pulses at a wavelength of 1.03 μm with more than 70 W of power, not simultaneously available with any other output.
5. Provide one additional output (O5) of 50 femtoseconds pulses at a wavelength of 2 μm, with at least 4 W of power, simultaneously available with O1, O2 and O3.
Background and Context
Intense ultrashort laser pulses are uniquely capable of unravelling the properties of materials, especially “quantum materials”, that is those where correlation between the material’s constituent elements determine the material’s advanced function. These materials’ properties often manifest at the nanometer scale all the way up to micrometer and macroscopic scales, as well as across a broad range of light frequencies. Probing these materials requires advanced intense laser sources that operate at high repetition rate (> 100 kHz) and across a large spectral range (from ultraviolet up to mid-infrared).
Femtosecond, high-energy and high-average-power lasers based on Ytterbium technology are ideal pump lasers to develop such multi-frequency platform. These lasers generate intense pulses at a fixed near-infrared wavelength. Frequency conversion is conventionally achieved with nonlinear Optical Parametric Amplification, but the marketed solutions provide only limited spectral coverage. Covering the desired range, spanning the ultraviolet to the mid-infrared, requires fractional solutions, with consequently lower efficiency. We seek a new cohesive technology to meet this challenge.
We anticipate such a laser platform will redefine the state-of-the art will be marketable in the rapidly growing field of ultrafast lasers at large. Aside from obvious interest in physics / engineering or chemistry departments around the world, such a widely tunable system is also relevant to biological and medical research.
