TOPTICA now introduces it's latest ECDL model: the DL pro 780. A sound
concept together with new techniques in mechanical engineering, allow
for the most stable external cavity diode laser commercially available.
At the same time the DL pro is very easy to operate and tune:
Key specifications:
- Alignment-free coarse tuning range: 30 nm
- High quality AR coated diode
- Optical output power: up to 80 mW
- Continuous modehop-free tuning range: > 50 GHz
- Narrow linewidth: ~ 500 kHz
- Frequency modulation: AC + DC FET current control (Bias-T option integrated)
- Highest intrinsic frequency stability
The DL pro 780 combines extended continuous modehop-free frequency
tunability and highest stability, two characteristics of ECDLs that
were previously mutually exclusive. To achieve this, TOPTICA completely
redesigned and optimized the optomechanical set-up while maintaining
basic advantages of the Littrow-Haensch design. The novel engineering
approach as well as innovative manufacturing techniques lead to a
strongly increased performance in many respects. The compact and stable
external cavity resonator has its first grating resonance frequency
above 3.5 kHz. This provides much reduced sensitivity against
environmental acoustic noise and allows for short term linewidths on
the order of 500 kHz. Special care has been taken in choosing
dimensions and materials to reduce frequency drifts caused by
variations of the ambient temperature (< 100 MHz/K). The laser can
be easily set to any wavelength within the specified tuning range
without any realignment of the external cavity. An optimized virtual
pivot point leads to a modehop-free scan range so far unmatched by any
other commercial Littrow-type grating stabilized diode laser. As the
ideal laser for many demanding applications, the DL pro 780 ensures
TOPTICA’s leadership in the market for external cavity diode
lasers for the years to come.
Typical applications for the DL pro 780:
- High resolution laser spectroscopy
- Laser cooling & BEC
- Electromagnetically induced transparency
- Magnetometry
