Page 3: Introduction
1 Introduction This manual contains information for operating the Vescent D2-200 DBR Laser Module. The D2-200 is a distributed Bragg reflector (DBR) diode laser that produces a near gaussian free-space output beam with a very low M and exhibits mode hop-free tuning over more than 25 GHz. -

50 Ω SMA terminator to avoid damage to the diode. Never connect or disconnect the D2-200 Laser Module to/from an energized laser controller. Always power down the laser controller completely before making connections to the D2-200. - Page 5 D2-200 User Manual Introduction The D2-200 is not intended for fail-safe operation in hazardous environments or life- threatening situations. The user assumes full responsibility for correct and safe usage of the D2-200 in accordance with any applicable laws, codes, regulations, and standards pertaining to their specific application.

50 Ω SMA terminator to avoid damage to the diode. Never connect or disconnect the D2-200 to an energized laser controller. Doing so can cause irreparable damage to the diode laser. Always power down the laser controller completely before making connections to this laser. - Page 9 Hardware 3. Temperature Control Port (Micro-D) The D2-200 has two temperature control stages: the housing stage (1) and the diode stage (2). Each stage has a thermo-electric cooler (TEC) that controls the temperature and an NTC thermistor (Rth) that monitors the temperature. A laser controller (e.g. D2-105 or SLICE-DLC) is required to stabilize the temperature of the D2-200.

Laser light is emitted from the laser through an aperture located on the front panel of the D2-200. Never view the laser from the above position. 4. Shutter The D2-200 has a rotating manual shutter that features a laser aperture and control lever, each of which are described below. 5. Laser Aperture The D2-200 has one laser aperture located on the front of the unit. -

8. Baseplate Slots The D2-200 comes with either an imperial or metric baseplate for mounting the unit to a matching optical breadboard. To mount the D2-200 to a breadboard, use the included cap screws and washers in the baseplate slots and securely fasten. -
Page 12: Getting Started
DBR laser diodes are fabricated with the feedback grating patterned directly adjacent to the gain region of the diode. The cavity of the D2-200 is short with no moving tuning element, making it highly immune to vibrations and acoustic perturbations. -

The D2-105 will turn on and the Power light will light up. 3.3.2 Temperature Stabilization If your D2-200 was purchased with a D2-105, then the D2-105 is set to the correct temperature settings for your laser. If your D2-105 was purchased separately, refer to Section 4 to configure the temperature settings. -
Page 14: Starting Laser Emission
D2-200 User Manual Getting Started • In the supplied D2-200 test documentation, find the Maximum Current on the Laser Module table. • Turn the D2-105 Current Limit Set knob to set I at or below the Maximum Current. I protects the diode from overcurrent by shunting excess current through a transistor to ground. -
