Key Features
- Tunable grating stabilized Diode Laser DL 100 in Littrow configuration
- Tunability typically +/- 7 nm, depending on the implemented laser diode
- Any wavelength within the tuning range is selectable (no spectral gaps)
- Single-mode operation also for many multi-mode laser diodes due to the grating set-up
- Construction made from high quality, heat-conducting, flexible metal
- Excellent passive temperature stability, active control by thermoelectric element (TEC)
- Flexure joints for elastiticity with good mechanical stability at the same time
- Precision adjustment screw for prealignment
- Laser diode can be chosen from a broad range of commercial suppliers, easy to change
- No need for expensive anti-reflection coating of the laser diode facet
- Laser diode potential is floating, no mains noise, laser diode can be changed
- Massive base block acts as heat reservoir (water cooling also possible, if neccessary)
- Relay short-circuit for laser diode protection during transport
