One OPA + One SHG ：Six Frequency Octaves from 315 to 2820 nm
Y-LASER is pleased to introduce the AURORA-HP + AU/SHG high-energy tunable femtosecond source, an integrated OPA + SHG platform that translates a fixed 1030 nm Yb output into continuous wavelength coverage from 315 to 2820 nm. With Signal tuning from 630 to 1030 nm, Idler tuning from 1030 to 2820 nm, SHG extension into 315–630 nm, 9.88% Signal peak efficiency, 4.85% Idler peak efficiency, 2.66% SHS peak efficiency, and 0.84% RMS power stability over 24 hours, the system provides a flexible and stable source for UV-Vis TA, Vis-NIR pump-probe, SWIR ultrafast spectroscopy, photochemistry, biological chromophore dynamics, and deep-UV ultrafast research.
Femtosecond Lasers and Ultrafast Spectroscopy — Optical Parametric Amplifiers (OPAs): Giving a 1030 nm Yb Master "Any Color It Needs"
Y-LASER is pleased to share a new delivery of a high-repetition-rate few-cycle femtosecond source: the HELIOS-40W-HP high-power Yb femtosecond master laser integrated with the HYPERION-G-HE multi-pass cell post-compressor. Starting from 43.8 W, 217.5 fs, and 438 µJ at 100 kHz, the system compresses the pulse to 36.2 fs while delivering 38 W average power, 380 µJ pulse energy, 95% transmission, 10.5 GW peak power, and 0.064% RMS stability over 24 hours. This Yb + MPC platform provides a stable and scalable driver for high-harmonic generation, EUV/VUV coherent sources, attosecond science, TR-ARPES, strong-field physics, and ultrafast electron diffraction.
Room-Temperature THz Source Breaks 0.4 % Conversion Efficiency in LiNbO₃--Y-LASER HELIOS-20W-HE Enables mJ-Class Short-Pulse Pumping at 10 kHz
Record 0.4% THz conversion efficiency & 51.7 mW average power — achieved by BUAA's Prof. Xiaojun Wu team using the HELIOS-20W-HE as the stable pump source (2 mJ / 226 fs / 10 kHz / 0.12% RMS over 24h), with AURORA-H-HP OPA delivering the <55 fs EOS probe (650–2600 nm tuning) and HYPERION-G MPC enabling 249 fs → 33.4 fs compression at 93% throughput. The reflective echelon route decisively outperforms gratings under short-pulse, mJ-class conditions — a systematic benchmark that moves strong-field THz from lab bottleneck toward engineering deployment.
Femtosecond Lasers and High-Repetition-Rate Few-Cycle Sources
Y-LASER is pleased to share a new delivery of a high-repetition-rate few-cycle femtosecond source: the HELIOS-40W-HP high-power Yb femtosecond master laser integrated with the HYPERION-G-HE multi-pass cell post-compressor. Starting from 43.8 W, 217.5 fs, and 438 µJ at 100 kHz, the system compresses the pulse to 36.2 fs while delivering 38 W average power, 380 µJ pulse energy, 95% transmission, 10.5 GW peak power, and 0.064% RMS stability over 24 hours. This Yb + MPC platform provides a stable and scalable driver for high-harmonic generation, EUV/VUV coherent sources, attosecond science, TR-ARPES, strong-field physics, and ultrafast electron diffraction.
Femtosecond Lasers and Tunable Ultrafast Spectroscopy
Y-LASER is pleased to share a new delivery of the HELIOS-20W-HE femtosecond master laser integrated with the AURORA-HE OPA and SHG module. The system provides continuously tunable femtosecond output from 315 to 2600 nm, with 2.16 mJ pulse energy, 230.5 fs pulse duration, 0.145% RMS master-laser stability over 24 hours, 9.2% peak Signal conversion, 5.76% peak Idler conversion, and 0.6623% RMS OPA stability over 24 hours. One integrated platform now supports UV-Vis transient absorption, NIR and SWIR ultrafast spectroscopy, perovskite and 2D-material studies, organic photovoltaics, and high-repetition-rate material screening on a single optical bench.
Femtosecond Lasers and Few-Cycle Pulse Science
Y-LASER is pleased to share a new delivery case of the HELIOS-20W-HE high-energy femtosecond laser combined with the HYPERION-G-HE multi-pass cell post-compressor. Starting from a 1030 nm Yb femtosecond master delivering 2.15 mJ, 226.6 fs, and 0.035% RMS stability over 24 hours, the system compresses the pulse to 40.4 fs while preserving 1.89 mJ pulse energy, 95.97% transmission, 46.8 GW peak power, and 99% beam ellipticity. This Yb + MPC platform bridges the gap between industrial femtosecond lasers and few-cycle science, providing a powerful and stable driver for HHG, EUV/XUV generation, attosecond science, strong-field physics, and ultrafast electron diffraction.
High-Power Yb Femtosecond Lasers and OPA-Pumped Ultrafast Spectroscopy
Y-LASER is pleased to share a new delivery case of the HELIOS-10W-HE high-power Yb femtosecond master laser for OPA-pumped ultrafast spectroscopy. With factory-measured performance of 1.13 mJ, 228 fs, 11.2 W at 10 kHz, 0.08% RMS power stability over 48 hours, near-diffraction-limited beam quality of M² ≈ 1.09, and an integrated pulse picker covering 1 Hz to 100 kHz, HELIOS-10W-HE provides one stable master source for OPA pumping, white-light continuum generation, TA pump-probe experiments, high-repetition-rate spectroscopy, and single-shot triggered measurements. This platform helps ultrafast spectroscopy labs improve signal stability, experimental flexibility, and long-term data quality across perovskites, semiconductors, 2D materials, and quantum dots.
Sub-Kilowatt-Class Yb Femtosecond + Multi-Pass Cell Post-Compression
Y-LASER is pleased to share our latest progress in sub-kilowatt-class femtosecond post-compression. In a recent on-site acceptance test, the HYPERION-G-HE multi-pass cell compressor was validated at 1 MHz / 512 W injection, delivering 497.7 W average power, 46.4 fs pulse duration, 97.2% transmission efficiency, and 0.33% RMS power stability over 16 hours. This result demonstrates a scalable path from high-power Yb femtosecond lasers to sub-50 fs, high-flux drivers for HHG, XUV/EUV generation, attosecond science, TR-ARPES, coherent imaging, and next-generation ultrafast applications. As femtosecond platforms continue scaling toward the kilowatt level, Y-LASER is committed to building reliable, industrial-grade laser infrastructure for frontier science and advanced photonics.
Full-Spectrum Femtosecond OPA — From 315 nm UV to 10 µm Deep Mid-IR on a Single Optical Table
We are excited to share Y-LASER’s latest full-spectrum femtosecond OPA platform, designed for next-generation ultrafast spectroscopy. Driven by a single HELIOS-20W-HP femtosecond master laser, this system integrates dual AURORA-HP OPAs with SHG and DFG modules to deliver continuously tunable femtosecond output from 315 nm UV to 4.3 µm mid-IR, with a clear modular path toward 10 µm deep mid-IR. By enabling independent UV/Vis, NIR, MIR, and deep-MIR beamlines on one optical table, the platform supports advanced studies in transient absorption, pump-probe spectroscopy, 2D-IR, perovskite solar cells, organic photovoltaics, semiconductor dynamics, and catalytic interfaces. This delivery marks an important step toward making full-spectrum ultrafast spectroscopy more integrated, stable, and accessible for frontier research labs.
