The accessible wavelength ranges from 680 to 1080 nm and the maximum pulse energy at 800 nm is 44 nJ at the laser output.
Quantify the maximum pulse width at this moment d trans(t I).
Maximum pulse duration at this power level was 5 ms.
The system delivered a train of pulses with a Gaussian beam profile, the wavelength was centered at 800 nm with maximum pulse energy of 2 µJ and a full-width-at-half-maximum pulse duration of 200 to 300 femtoseconds (10−15 s).
The stabilities of these self-similar pulses, even at the maximum pulse compression, are then demonstrated under the perturbations of the additive white noise and the higher-order nonlinear effects such as self-steepening and self-frequency shift accompanying the severe pulse compression.
A maximum pulse energy of 2.51 mJ was achieved at repetition rate of 50 Hz, corresponding to a minimum pulse duration of 88 ns.
A pulse width of about 90 ns and the maximum pulse energy of about 300 mJ were achieved at 10.59 μm in SLM and TEM00 mode.
The output beam from the Mira (800 nm wavelength, 135 fs full-width at half-maximum pulses, 76 MHz repetition rate, and 10 nJ maximum pulse energy) was expanded and spatially filtered to ensure optimal focusing.
Due to directional loading in tonometry, pulse amplitude maxima was observed to occur at a significantly lower compression level (around 31%) than previously reported, which can impact blood pressure calibration approaches based on maximum pulse pressure recordings.
At this point, the pulse has effectively an order of magnitude more energy than the maximum pulse energy that could be used with a standard focus (104 µJ) and still maintains a symmetric profile centered on the focal plane.
