![]() The ModBox-OSB integrates laser chain such as High Energy Lasers (HEL) lasers or Spectral Beam Combining laser architectures (SBC). The ModBox-OSB contains a single-tone RF generator, white noise sources or PRBS sources. A number of side bands are created over a spectral width that can reach several hundreds GHz. The Optical Spectral Broadening ModBox-OSB achieves the broadening of an optical signal by modulating its phase via the mean of a very efficient LiNbO 3 phase modulator. The ModBox works at any wavelength, and for an optical pulse train repetition which is externally triggered up to gigahertz repetition rates. The available optical shapes are gaussian and square waveform. The ModBox-OPG is a family of optical pulse generation units which generate pulses with durations from 30 ps to hundreds of nanoseconds, and with very high extinction ratio. The short pulse generation is based on the combination of a high-performance continuous laser source combined with a large bandwidth modulation. The system is available at 1030 nm, 1053 nm and 1064 nm, it allows to generate custom shaped optical pulses with high stability and high extinction ratio and with durations from 125 ps to 100 ns. The iXblue ModBox-OFE is a complete front end laser system designed to be used as a seed source in high energy density laser facilities. The RP Photonics Buyer's Guide contains 139 suppliers for pulsed lasers. with laser diodes in quasi-continuous-wave operation.ĭifficulties with Continuous-wave Operation Relatively long pulses can be generated e.g.Gain-switched semiconductor lasers are suitable for nanosecond or picosecond pulses with relatively low energy (→ picosecond diode lasers).Their pulse energies are generally quite small, and the pulse repetition rate is usually in the megahertz or gigahertz region.įor higher pulse energies (roughly an order of magnitude more), one may use a cavity-dumped laser. ![]() Ultrashort pulses with durations in the picosecond or femtosecond domain are usually generated with mode-locked lasers, which may be solid-state bulk lasers, fiber lasers or semiconductor lasers.copper vapor lasers) are also driven with current pulses and could normally not work in continuous-wave operation. nitrogen lasers) and metal vapor lasers (e.g. They are pumped with rather short electric pulses. Excimer lasers are used for generating intense nanosecond pulses in the ultraviolet spectral region. ![]()
