Claims
- 1. A diode laser comprising:(1) an output surface; (2) a reflection surface substantially parallel to, and offset from, said output surface, the output surface and reflection surface defining a laser cavity; (3) a first DBR grating with the laser cavity, and disposed 45 degrees to the local longitudinal axis of the laser cavity; and (4) a second DBR grating within the laser cavity, and disposed at 45 degrees to the laser cavity.
- 2. The diode laser of claim 1, wherein the grating period of the first DBR grating is different from the grating period of the second DBR grating.
- 3. The diode laser of claim 1, further comprising a current-pumped stripe region.
- 4. The diode laser of claim 3, wherein the first DBR grating abuts at least a portion of the current-pumped stripe region.
- 5. The diode laser of claim 3, wherein the first DBR grating is separated from the end of the current-pumped stripe region by a spacer region.
- 6. The diode laser of claim 5, wherein the spacer region is current-pumped.
- 7. The diode laser of claim 5, wherein the current-pumped striped region has a predetermined width, wherein the spacer region has a predetermined length, and wherein the length of the spacer region is about three times the width of the current-pumped stripe region.
