WAVELENGTH STABILIZED DIODE LASER MODULE WITH LIMITED BACK REFLECTION
A module is configured with a housing enclosing a diode laser. Fast and slow axes collimators are located behind the rear facet of the laser, which along with a front facet, defines an intra- cavity of the laser. The facets are partially transmissive to light and therefore emit laser light. A wavele...

Summary: | A module is configured with a housing enclosing a diode laser. Fast and slow axes collimators are located behind the rear facet of the laser, which along with a front facet, defines an intra- cavity of the laser. The facets are partially transmissive to light and therefore emit laser light. A wavelength selective optical element is aligned with the collimators and configured to reflect light emitted through the back facet and processed by collimators back into the intra-cavity, As a result, the laser beam is emitted through the front facet at a wavelength locked on the desired wavelength of the optical element. A delivery fiber is mechanically coupled to the front facet of diode laser and configured to receive and guide the emitted laser beam along the path of light. |
