Laser Active Optical Systems (LAOSs) for Material Processing [PDF]
MicromachinesThe output energy of Laser Active Optical Systems (LAOSs), in which image brightness is amplified within the laser-active medium, is always higher than the input energy. This contrasts with conventional optical systems (OSs).

Modulation instability in 
high power laser amplifiers [PDF]
Optics Express, 2010 The modulation instability (MI) is one of the main factors responsible for the degradation of beam quality in high-power laser systems. The so-called B-integral restriction is commonly used as the criteria for MI control in passive optics devices.

Optical Bistability in Semiconductor Laser Amplifiers
Optical Bistability, 1988 It has recently become clear that OB in semiconductor laser amplifiers has many potential advantages for applications in optical logic and signal processing. Foremost among these advantages may be listed (i) ready availability (compared with other bistable devices [1]), (ii) wavelength compatibility with optical communications systems, (iii) inherent ...
