Abstract
<1.25) despite a relatively small cavity length (e.g., 50-53 mm) for a high (e.g., ≧10 watt) output power device. This enables the construction of physically smaller laser and optical assemblies without sacrificing performance. Reduction of optical photonic interference, which can impair imaging performance, is also facilitated. Laser and optical assemblies may utilize an aperture defined within an optical barrier element to reduce the divergence of the light beam emanating from a diode-pumping laser.
