Abstract
A process for creating a stabilized diode laser device is disclosed, where the stabilized diode laser device includes a unibody mounting plate and several chambers aligned along a transmission axis. Various optic components are placed in the chambers, and based on a transmission through the chambers, the optic components are aligned and secured within the chambers.
Claims10
A process comprising:
- providing a unibody mounting plate with chambers aligned along a transmission axis;
- securing a laser diode in a first chamber of the unibody mounting plate;
- activating the laser diode to transmit light along the transmission axis;
- placing components in their respective chambers including:
- placing a collimating lens in a second chamber;
- placing a volume Bragg grating in a third chamber;
- placing a first optical isolator in a fourth chamber;
- placing a first beam expander lens in a fifth chamber;
- placing a second beam expander lens in a sixth chamber;
- placing a second optical isolator in a seventh chamber;
- and
- placing a bandpass filter in an eighth chamber;
- monitoring spatial and spectral characteristics of an output from each chamber;
- determining whether each optic component is aligned based on the monitored spatial and spectral characteristics of the output from each chamber;
- aligning the optic component in response to determining that the optic component is not aligned;
- securing each optic component in its respective chamber in response to determining that the optic component is aligned;
- and
- deactivating the laser diode upon securing each optic component in its respective chamber.
