Abstract

An assembly includes an etalon assembly for dynamically locking a frequency of an optical beam to a set frequency, the etalon assembly being external to a laser source assembly that outputs the optical beam. The etalon assembly includes an etalon that receives the optical beam and generates via interference effects a transmission beam, the etalon having a thermal tuning range greater than one half of a free spectral range of the etalon. The etalon assembly also includes an etalon heater mounted to the etalon such that the etalon heater is configured to adjust the temperature of the etalon. The assembly includes a controller configured to retrieve calibration data based on the set frequency, calculate a set temperature for the etalon using a thermal tuning algorithm and the calibration data, and control the etalon heater such that the etalon has a temperature equal to the calculated set temperature.

Abstract

A laser module comprising a laser device attached to a heat sink that is configured to provide a relatively low thermal resistance for thermal management of the laser device, and an aggregate coefficient of thermal expansion (CTE) that is substantially matched to the CTE of the laser device for reducing stress caused by thermal cycles. The heat sink includes a shell made out of a first material, and a core situated within the shell and made out of a second material distinct from the first material of the shell. By properly selecting the first and second materials, configuring the thickness of the shell directly under the location to which the laser device will be attached with respect to the thickness of the core, the desired effective or aggregate CTE and thermal resistance of the heat sink may be achieved.
