Layer Design of Highly Efficient Optically Pumped Semiconductor Disk Lasers
نویسنده
چکیده
Optically pumped semiconductor disk lasers (OPSDLs) with extended cavities are surfaceemitting laser devices which efficiently convert the low-beam-quality emission of a pump laser to a high-beam-quality circular non-astigmatic laser emission. Furthermore, the extended cavity can be utilized for intra-cavity second harmonic generation by insertion of nonlinear optical crystals. By that way, the range of usable wavelengths is drastically expanded from the near infrared to the visible range of the optical spectrum [1–5].
