“…Although these aspects of DCS make it an attractive option for remote sensing in field applications, the full quantitative performance of DCS has only been demonstrated with stabilized frequency combs phase-locked to laboratory references. Recent advances in fiber-based frequency combs can now provide broadband near-infrared light in relatively robust packages that are capable of operation outside laboratory environments [2][3][4][5][6]. However, an accurate DCS instrument requires: i) sub-radian mutual optical coherence between the combs to achieve high SNR, comb-tooth resolved spectra, ii) absolute comb-tooth linewidth that is much less than the desired spectral resolution (which is not guaranteed solely by condition (i)), and iii) absolute comb-tooth frequency accuracy to avoid the need for separate spectral frequency calibration.…”

A fieldable dual-comb spectrometer is described based on a "bootstrapped" frequency referencing scheme in which short-term optical phase coherence between combs is attained by referencing each to a free-running diode laser, whilst high frequency resolution and long-term accuracy is derived from a stable quartz oscillator. This fieldable dual-comb spectrometer was used to measure spectra with full comb-tooth resolution spanning from 140 THz (2.14 µm, 4670 cm -1 ) to 184 THz (1.63 µm, 6140 cm -1 ) in the near infrared with a frequency sampling of 200 MHz (0.0067 cm -1 ), ~ 120 kHz frequency resolution, and ~ 1 MHz frequency accuracy. High resolution spectra of water and carbon dioxide transitions at 1.77 µm, 1.96 µm and 2.06 µm show that the molecular transmission acquired with this fieldable system did not deviate from those measured with a laboratory-based system (referenced to a maser and cavitystabilized laser) to within 5.6×10 . Additionally, the fieldable system optimized for carbon dioxide quantification at 1.60 µm, demonstrated a sensitivity of 2.8 ppm-km at 1 s integration time, improving to 0.10 ppm-km at 13 minutes of integration time.Work of the U.S. Government and not subject to copyright.

“…The designed structure ( Figure 13(c)(d)) was comprised of two separate compartmentsone for optics and the other for electronics-with a thermal barrier in between to reduce the heat crosstalk between optical components and electrical devices. [22] Laboratory tests were conducted to confirm that the oscillator emitted ultrashort pulses of 350 fs duration at a 25 MHz repetition rate. The average output power was measured to be ~14 mW for a pump power of 600 mW.…”

This article stared with a brief description of the propagation of femtosecond laser. Filament formation and spectral broadening are emphasized. Its novel characters bring the outstanding aspects of femtosecond lidar. Then the applications of femtosecond lidar in atmosphere remote sensing are discussed, namely Gas-phase Remote Sensing, Cloud Remote Sensing, Pollutants Remote Sensing and Bioaerosol Remote Sensing. In the end, two femtosecond laser systems used out of lab are introduced.

“…Such frequency combs have to survive challenging environmental conditions, in particular high-energy radiation. In this context, DPSSL frequency combs constitute a valuable alternative to fiber combs that are generally the preferred choice for space applications [71]. Buchs et al have proved the capability of a modelocked Yb:KYW DPSSL to sustain a dose of gamma and protons radiation corresponding to more than five years in outer space on a highly elliptic orbit around Earth corresponding to a possible future candidate mission for a frequency comb in space [58].…”

Optical frequency combs have been revolutionizing many research areas and are finding a growing number of real-world applications. While initially dominated by Ti:Sapphire and fiber lasers, optical frequency combs from modelocked diode-pumped solid-state lasers (DPSSLs) have become an attractive alternative with state-of-the-art performance. In this article, we review the main achievements in ultrafast DPSSLs for frequency combs. We present the current status of carrier-envelope offset (CEO) frequency-stabilized DPSSLs based on various approaches and operating in different wavelength regimes. Feedback to the pump current provides a reliable scheme for frequency comb CEO stabilization, but also other methods with faster feedback not limited by the lifetime of the gain material have been applied. Pumping DPSSLs with high power multi-transverse-mode diodes enabled a new class of high power oscillators and gigahertz repetition rate lasers, which were initially not believed to be suitable for CEO stabilization due to the pump noise. However, this challenge has been overcome, and recently both high power and gigahertz DPSSL combs have been demonstrated. Thin disk lasers have demonstrated the highest pulse energy and average power emitted from any ultrafast oscillator and present a high potential for the future generation of stabilized frequency combs with hundreds of watts average output power.
