Abstract Often one wants a laser amplifier system to produce an output pulse of a specific form, e.g., time shape, energy, etc. Given any potential amplifier configuration one needs to find the proper input pulse which, when propagated through the amplifier system, results in the desired output pulse.

The performance of a ruby laser amplifier is described and compared with a theoretical model. The ruby laser amplifier was driven by a Q-switched laser oscillator with a stable output, whose properties are due, in part, to a newly developed output coupler and a spinning roof-top prism for Q-spoiling.

Nd:MgO:LiNbO_3 waveguide laser and amplifier
Optics Letters, 1990Nd:MgO: LiNbO3 is a promising material that combines the good laser gain of Nd3+with the electro-optic and nonlinear properties of LiNbO3.1-3 In a waveguide configuration, this combination offers the possibility of realizing highly efficient laser-diode-pumped lasers and amplifiers, self-frequency doubled lasers, integrated laser/modulator structures ...

A series of models is developed that describes a Ho:Tm laser, and predictions from these models are compared with experimental measurements for a variety of Ho:Tm:YLF amplifiers. Modeling is complicated by the plethora of required parameters needed to describe the dynamics of the Ho:Tm laser system versus the paucity of measured parameters.

Above-threshold laser amplifier
Physical Review Letters, 1991We have measured gain profiles by light-beating techniques for an argon-ion laser operated above threshold. The observed behavior is interpreted by developing a theory which incorporates four-wave mixing of signal and image frequencies. The gain shows the typical characteristics of a second-order phase transition.

Experimental results are presented on the operational characteristics of GaAs laser amplifiers very closely coupled to a laser oscillator. The separation between the oscillator and the amplifier was varied from 0.2 to 2.0 microns. The amplifiers were made by lapping one end at an angle of 10 to 15 degrees.

A laser-amplifying device is proposed which is based on the stimulated decay of excitons in a pure crystal. An estimate is made of the gain of the device. At a typical frequency the gain is found to be appreciably large, thus suggesting practical application of the laser amplifier.

Laser-amplifier gain and noise
Physical Review A, 1993A theoretical study is presented of the gain and the noise spectra of laser amplifiers at pumping rates both above and below the oscillation threshold. The theory is valid for both class- A and class-B laser systems, where the decay rate of the collective atomic dipole moment greatly exceeds the decay rates of the atomic population inversion and the ...

Amplifier/compressor fiber Raman lasers
Annual Meeting Optical Society of America, 1987When pump and Stokes pulses copropagate in a fiber Raman laser (FRL), the weaker Stokes spectrum is severely broadened through pump-induced cross-phase modulation (XPM).1 Thus, in an FRL during Raman amplification, the pulse is chirped through XPM, and then the linear anomalous dispersion of a fiber can compress the pulse.

Ultrafast disk lasers and amplifiers
SPIE Proceedings, 2012Disk lasers with multi-kW continuous wave (CW) output power are widely used in manufacturing, primarily for cutting and welding applications, notably in the automotive industry. The ytterbium disk technology combines high power (average and/or peak power), excellent beam quality, high efficiency, and high reliability with low investment and operating
