Stabilization of a semiconductor disk laser using an intra-cavity high reflectivity grating.
We demonstrate the use of a High Reflectivity Grating (HRG) as an intra-cavity element in a Semiconductor Disk Laser (or Vertical External Cavity Surface Emitting Laser) to stabilise its emission wavelength and polarization characteristics. Operation at 1058nm with up to 645mW of pump-limited output power and an M(2)~1.4 is achieved. We also show that this scheme permits tunable single-frequency operation.
