“…Sub-500 fs pulses were realized in the first soliton Tm fiber laser back in 1995 [2]. Pulse durations as short as ∼50 fs have been achieved in dispersion-managed cavities, with pulse energy <1 nJ [3,4]. A cavity containing a grating and telescope combination for the normal-dispersion segment generated 5.4-nJ and 216-fs pulses [5].…”

We report a study of a mode-locked thulium (Tm) fiber laser with varying normal dispersion. It is difficult to reach the high-energy dissipative-soliton regime due to the anomalous dispersion of most fibers at 2 μm. With large normal dispersion, the laser exhibits elements of self-similar pulse evolution, and is the first Tm fiber laser to achieve the performance benefits of normal-dispersion operation. The laser generates 7.6 nJ pulses, which can be dechirped to 130 fs duration. The resulting peak power is 4 times higher than that of previous Tm fiber lasers.

“…However, the property of low dispersion has been overlooked in the previous research on ZBLAN fibers. Recently, the authors demonstrated a thuliumdoped fiber laser oscillator based on ZBLAN fibers pumped by a Ti:sapphire laser, and pulses as short as 45 fs are generated [27].…”

“…Two types of oscillators are demonstrated using two different types of fibers. One is made with a single-mode ZBLAN fiber, which is a system similar to that presented in [27] but the Ti:sapphire laser used as the pump is replaced with laser diodes. The other is a completely new system built with doubleclad ZBLAN fibers.…”

Fluoride glass known as ZBLAN is well known for high transparency in the infrared region and is a promising candidate for the host material for infrared lasers. Furthermore, low material dispersion of ZBLAN glasses around 2-μm wavelength region suggests the usefulness of ZBLAN fibers for developing ultrafast fiber lasers. Based on these considerations, we have conducted a detailed study of ultrashort fiber laser oscillators based on thulium-doped ZBLAN fibers. Two types of diode-pumped, modelocked oscillators are demonstrated using single-mode ZBLAN fibers and double-clad ZBLAN fibers. The oscillator with singlemode ZBLAN fibers generate stable output pulses at 67.5-MHz repetition rate with the average output power of 19 mW. The broad spectra spreading over 300 nm enabled the generation of pulses as short as 45 fs in 2-μm region. The oscillator with doubleclad ZBLAN fibers was built with a multimode laser diode as the pump source and was successfully mode-locked at the pump power of 1.04 W. The output pulses with the spectrum extending over 150 nm are compressed to 90 fs.

“…Due to the lack of commercially available mid-IR resonant gain media, there have been only a few reports of fs-lasers developed beyond a wavelength of 2.5 μm [3,4]. Although 2 μm fiber lasers have been developed in the fs regime [5], to go further into the mid-IR requires frequency conversion. Different frequency generation (DFG) is an option [6], but typically has low efficiency Synchronously pumped optical parametric oscillators (OPOs) are recognized as useful laser sources for the production of tunable output pulses over a broad wavelength range including the mid-IR [7][8][9].…”

An idler-resonant femtosecond optical parametric oscillator (OPO) with near-diffraction-limited beam quality (M 2~1 .05) at ~2.4 μm is demonstrated. The OPO is synchronously pumped by a femtosecond Yb:fiber amplifier system providing 130 fs pulses with an average power of 4.5 W at 1050 nm and delivers 90 fs pulses with maximum average powers of 600 mW for the idler and 670 mW for the signal. Tunability, is demonstrated across idler (signal) wavelengths from 2.2-2.6 μm (1.76-2.0 μm), limited only by the OPO mirrors. As a demonstration of the utility of the source, the idler pulses are used to generate a supercontinuum from 1600 nm to 3200 nm in a silicon-core fiber.
