“…We would like to note that single-grating pulse stretchers/compressors have been developed previously, but only for very specific applications (chirped pulse amplification) and without these convenient features. [4] The use of a corner cube and a single prism to build a complete pulse compressor appears not to have been mentioned previously, to the best of our knowledge.…”

We have designed and demonstrated a very simple and compact ultrashort-pulse compressor using a single prism and a corner-cube. Our design is significantly easier to align and tune compared with previous designs. Angle-tuning the prism wavelength-tunes, and translating the corner cube varies the group-delay dispersion over a wide range. When tuned, the device automatically maintains zero angular dispersion, zero pulse-front tilt, zero spatial chirp, and unity magnification. The device can easily be built so that its output beam remains collinear with the input beam, and when the input beam or pulse compressor moves, the input and output beams remain collinear.

“…The pulses from the last amplifier are finally magnified with an imaging telescope and sent to a folded Treacy-type grating compressor that is matched to the stretcher [57,134]. Compared to prior experiments described in [49], the compressor was re-built in vacuum (Fig.…”

“…In the folded design of the PFS pump compressor ( [57,134]) with just one grating, a horizontal and a vertical roof mirror (RM), the described non-parallelism can be realized by a misalignment of the horizontal RM. An interesting feature of the setup is that if the overall alignment is not exceptionally poor, no significant angular dispersion can develop in the vertical plane: in case that the grooves of the grating are not exactly perpendicular to the table, an angular dispersion component in the vertical dimension is created.…”

“…For example, to allow amplification in Yb fiber at 1030 (1050) nm, the peak can be centered at 1027 (1065) nm, with 14 (11.5) mW of power in a 70 (100) nm bandwidth. The HNLF output is then coupled into a core-pumped ytterbium fiber amplifier that provides an amplified average power of 400 mW at a pump power of ~ 1 W. For environmental stability, the entire fully-spliced amplifier and HNLF apparatus is placed inside a small box.Using a volume phase holographic single grating compressor [16], the amplified 1040 nm pulses are compressed with 75% power efficiency to 73 fs duration, as measured by SHG-FROG (Fig. 2).…”

Received Month X, XXXX; revised Month X, XXXX; accepted Month X, XXXX; posted Month X, XXXX (Doc. ID XXXXX); published Month X, XXXXWe present a multibranch laser frequency comb based upon a 250 MHz mode-locked erbium-doped fiber laser that spans more than 300 terahertz of bandwidth, from 660 nm to 2000 nm. Light from a mode-locked Er:fiber laser is amplified and then broadened in highly-nonlinear fiber to produce substantial power at ~1050 nm. This light is subsequently amplified in Yb:fiber to produce 1.2 nJ, 73 fs pulses at 1040 nm. Extension of the frequency comb into the visible is achieved by supercontinuum generation from the 1040 nm light. Comb coherence is verified with cascaded f-2f interferometry and comparison to a frequency stabilized laser.OCIS Codes: 190.7110, 060.2320 The Er:fiber-based laser frequency comb is a technologically mature tool for precision metrology with benefits of long-term reliability and relatively low cost. However, in some applications, such as direct frequency comb spectroscopy [1, 2] Here, we present a technique for generating a visible light frequency comb from a mode-locked erbium laser that is self-referenced and frequency-stabilized using established techniques. In nonlinear fiber we shift significant pulse energy to the 1 μm region, where it is amplified with a core-pumped Yb:fiber amplifier [7,8,9,10,11]. The amplifier output is then compressed to provide a 73 fs pulse, which is spectrally broadened to below 650 nm using microstructured fiber. Significantly, we verify that the coherence of the original Er:fiber source is transfered to the amplified 1040 nm pulses, and that with subsequent nonlinear broadening the system provides a multibranch LFC with nearly two octaves of bandwidth from 660 nm to beyond 2000 nm.Intense ultrashort pulses at 1.04 μm are generated from a 250 MHz mode-locked Er:fiber laser [12] using a series of amplifiers and nonlinear fibers, shown in Fig. 1. One third (35 mW) of the light produced by the Er:fiber laser is amplified in a core-pumped Er:fiber amplifier to an average power of 450 mW. Dispersion management and nonlinear pulse-shortening are achieved by carefully trimming the length of standard anomalous-dispersion single-mode fiber (SMF) between the laser and the gain fiber and by making use of a normal-dispersion Er:doped fiber [13] (nLight Er80 4/125). After recompressing the amplified pulses in SMF, a pulse duration of ~ 70 fs at 1580 nm is achieved as measured using second-harmonic generation frequency-resolved optical gating (SHG-FROG) [14].The erbium amplifier output is fusion spliced to a 5 cm long piece of solid-core highly nonlinear fiber (HNLF) [15] with dispersion of 7.7 (ps/nm)/km at 1600 nm, which is in turn coupled out by splicing to a length of SMF. This generates a supercontinuum with ~ 8 % of the 240 mW power coupled into the SMF falling between 1000 nm and 1100 nm. Within that range, the placement of the spectral peak can be refined by tuning the polarization state of light entering the Er:fiber amplifier and the HNL...
