Point Source (Hamble, UK) offers a 20-mW blue diode laser with a TEM00 true Gaussian beam, a higher power version of their range of iFLEX2000TM fiber-coupled lasers. The laser beam conditioning is performed using a single mode fiber, reducing beam astigmatism and spatial noise. The device employs a forward closed loop power control that resists optical feedback. Short-term amplitude noise is reduced and the stability of output is augmented. Applications include biomedical fluorescence imaging and optical media.
