“…This is due to the depletion of population inversion by the leading edge [15]. For the high-power saturated laser amplifiers, this pulse distortion can be compensated by a proper shaping of the input pulse [14][15][16].…”

A novel kind of all-solid photonic bandgap fiber (AS-PBGF) has been used in the master oscillator power amplifier structured Er/Yb-co-doped pulsed fiber amplifier to suppress the Yb band parasitic lasing for the power scaling and safety operation. To the best of our knowledge, this is the first time to report the use of AS-PBGF to suppress the Yb band parasitic lasing. The experimental results show that the Yb band parasitic lasing has been suppressed efficiently and the amplifier power has been raised dramatically with the utilization of AS-PBGF. An output power of 2.66 W was finally obtained without any unwanted parasitic lasing.

Abstract-We review recent advances in the development of high power short-and ultrashort pulsed Thulium-doped fiber amplifier (TDFA) systems seeded by semiconductor laser diodes at wavelengths around 2 µm. The diode-seeding and the master oscillator power amplifier (MOPA) design allow for the construction of extremely versatile laser systems that can operate over wide ranges of peak power, pulse energy and repetition rate in the ultrashort picosecond to the long nanosecond pulsed regimes. We present a record peak power of 130 kW and pulse energy of 5 µJ in picosecond mode, while demonstrating user-defined pulse-shaping capabilities at millijoule pulse energy levels in the nanosecond regime from essentially the same amplifier system. The system architecture as well as important design and power scaling considerations are discussed in detail. Additionally, we highlight recent results in the application of these MOPA systems and their high performance TDFA stages in such diverse application areas as next generation telecommunication networks, mid-infrared supercontinuum generation and mid-infrared gas detection in hollow-core photonic bandgap fibers.

“…The main parameters of the investigated laser diodes are presented in Table 1. Looking at the table and keeping in mind the absorption spectra of the active media (peak of absorption at 975 nm and FWHM 6 nm) [10] it seems that all of them, with the exception of the last one, can be used to pump the laser. Examining the power distribution in the beams at the output of the fibre, the instabilities in the beams of JenOptic diodes, shown in Fig.…”

“…There are many papers dealing with different active media and saturable absorbers meant for "eye−safe" microchip lasers [1][2][3][4][5][6][7][8][9][10][11][12][13]. The scientists put a lot of effort into develop− ing a more effective microchip laser with the maximum power or energy in the shortest possible pulse.…”

The paper describes practical application of pulsed microchip laser generating at 1535-nm wavelength to a laser rangefinder. The complete prototype of a laser rangefinder was built and investigated in real environmental conditions. The measured performance of the device is discussed. To build the prototype of a laser rangefinder at a reasonable price and shape a number of basic considerations had to be done. These include the mechanical and optical design of a microchip laser and the opto-mechanical construction of the rangefinder.
