Definitions
- the field of the invention is that of lasers with ultra-short pulse duration, typically less than 1 ⁇ s.
- Such laser pulses are obtained by means of pulse-pulse laser amplification equipment also known as a frequency drifting chain 100 (or CPA), which is an acronym for the expression “Chirped Dise Amplifier”.
- CPA frequency drifting chain 100
- a low energy, short duration laser pulse 10 provided by a generator 0 is:
- the stretching ratio is the ratio between the duration of the pulse after stretching and the duration of the pulse before stretching
- the stretched pulse 11 is then amplified by an amplifier 2 into a long-lasting pulse 12 of high energy; this amplifier 2 is typically constituted by a series of amplifiers in cascade,
- the pulse 12 stretched and amplified is then compressed by a compressor 3 into a pulse 13 at high peak energy and short duration.
- the pulse duration at the input and at the output of a CPA channel is close to the Fourier limit (between a few hundred and a few tens of fs typically).
- the compressor 3 makes it possible to compress pulses up to a few ns of pulse duration at the input of the compressor to a few hundred fs or even tens of fs at the output of the compressor.
- the compressor is a critical component in a frequency drift architecture because its optical components (compression networks, dihedral) must support the full average power and peak power of the laser after compression.
- Compression network is a diffraction grating used in a compressor.
- the compression ratio defined as the ratio between the duration pulse before compression and the pulse duration after compression can be very important, up to several tens of thousands (100,000 for example). In general, the compression ratio is equal to the stretching rate. This compression ratio sets the size of the compressor.
- the distance between the two networks 31, 32 is several meters. This little compact architecture can make the compression of the impulse unstable over time.
- this architecture is tuned on both networks
- a folded architecture as shown in Figure 3a can be used. It has the advantage of dividing by approximately two the distance between the optical elements, to facilitate the adjustments with the use of a single compression network 31 mounted on a single device 310 for dynamic adjustment in translation and in rotation (symbolized by two arrows), and focus the dynamic optimization settings on the single compression network.
- the ep thickness is also important, typically 10% of the length, to ensure a good wavefront quality at the output of the compressor. This thickness limits the possibility of cooling by the rear of the networks for the management of the thermal, especially in the case of pulses of high average power such as greater than 300 W at the input of the compressor, or high peak powers such as higher at 1 TW at the compressor output.
- the subject of the invention is a folded compressor for a predetermined drift rate drifting chain and comprising:
- a compression network positioned to receive an input pulse and an output pulse of the compressor, mounted on a dynamic adjustment device in translation and in rotation,
- the compression network and the dihedrons being configured to form on the compression network at least two stretched pulses. It is mainly characterized in that the compression network is divided into two compression subarrays with the same optical properties, mounted on said adjustment device:
- a first compression subarray of length L1 determined to completely contain the stretched pulses, but not the input and output pulses
- the two compression subarrays are placed side by side on a single adjustment device in translation and rotation.
- the lines of the two sub-networks are aligned with each other (to be parallel to each other) once and for all before they are installed in the compressor.
- the first compression sub-network has a thickness ep1
- the second compression sub-network has a thickness ep2 with ep2 ⁇ ep1.
- the compression sub-network supporting the high average power being of smaller length, its thickness is even smaller. This thinner thickness allows a better cooling of this sub-network, which reduces its sensitivity to damage as well as the deformation of the wavefront of the laser pulse at the output of the compressor.
- the input pulse typically has an average power greater than 300 W.
- the invention also relates to a frequency drift chain comprising a stretcher, an amplifier and a compressor as described.
- FIG. 1 already described schematically represents a frequency drifting amplifier chain according to the state of the art, on which is indicated the effect of each element on the pulses (energy as a function of time),
- FIG. 2 already described schematically represents a first example of a compressor with two compression networks according to the state of the art, seen in section,
- FIG. 3a already described schematically represents a second example of a collapsed compressor, comprising a single compression network according to the state of the art, seen in section and FIG. 3b shows the spatial distribution of the pulse on the single network,
- FIG. 4a diagrammatically represents an example of a collapsed compressor comprising two compression subarrays according to the invention, seen in section and FIG. 4b shows the spatial distribution of the pulse on these sub-networks.
- FIG. 3b shows the spatial distribution of a pulse on the single network 31 of a collapsed compressor 3 during its passage through the compressor.
- the pulse 12 forms on the compression network 31 of length L, height h and ep thickness: a T1 input spot, temporally stretched according to the wavelength, which
- T1 and output T1 pulses are located side by side (along the length L) of the T2, T3 pulses spectrally spread in the spatial domain by the network 31, as can be seen in FIG.
- length L of the single network 31 is much greater than the length of each network 31, 32 of a conventional architecture; the length L is at least equal to the sum of the lengths of the networks 31 and 32.
- the architecture of a collapsed compressor is modified to adapt more particularly to the case of a string having a high compression ratio (or stretching) in order to reduce the risks on this architecture in the case pulses with high average power in particular; but it is of course also usable in the case of pulses at low average power.
- the input pulses T1 and output T4 of the compressor being each sparsely spread over the network 31, the average power density and peak power on this area of the network are very important; the output pulse T4 temporally compressed is of course much more powerful than the input pulse T1 temporally stretched. Therefore, the limits in terms of resistance to the flow of the component are concentrated on this zone receiving T1 and T4, in fact mainly T4. But in case of damage, the entire network will have to be replaced.
- An example of a compressor according to the invention is described with reference to FIGS. 4a and 4b: the large single network 31 of FIG.
- a first compression subarray 31a completely comprising the spectrally stretched pulses T2 and T3 but not T1 or T4, and which is therefore of great length L1 even if L1 ⁇ L, which induces a high cost and a long duration of supply. It has a height h1 which is a priori identical to h, and a thickness ep1 a priori lower than ep since L1 ⁇ L.
- the average power density on this long sub-network 31a is small, limiting the risk of sub-network damage and wavefront deformation.
- a second compression subarray 31b which is backed by the T1 input and T4 output pulses (integers) of the compressor but not T2 or T3, and which can therefore be of shorter length L2 (L2 ⁇ L1) because of the spatial dimension of these pulses.
- L2 ⁇ L1 Typically (L1 / L2)> compression ratio. It has a height h2 which can be less than h1, and a thickness ep2.
- This sub-network 31b therefore supports a much higher average power density and thus concentrates all the risks of damage.
- Its length L2 is standard, its supply time and cost are lower, which reduces the disadvantages of possible damage.
- Such a compressor makes it possible to keep the advantages of the folded architecture, in terms of compactness, of adjustments - the two sub-networks 31a and 31b are placed on a common device 31 0 for adjusting in translation and in rotation - and stability.
- each new height dihedral doubles the number of pulses on the network 31 a.
- the set of stretched pulses are superimposed along h1 as can be seen in Figure 4b. If this number of stretched pulses has the consequence that h1> L1, then the thickness ep1 is of course determined as a function of h1, the largest dimension.
