DL-SHG pro – Tunable Diode Laser

TOPTICA’s DL SHG pro – frequency-doubled tunable diode laser.

UV, blue, green, yellow, orange wavelengths: 320 .. 650 nm
"One box" laser for mW power levels @ exotic wavelengths
Grating stabilized diode laser with resonant doubling stage
Single-frequency operation, linewidth < 500 kHz (typ.)
Probe beam output of fundamental laser
High power upgrade: TA SHG pro
Mode matching and beam shaping optics integrated
Optional fiber coupling of probe and/or SHG output beam

The DL SHG pro is a medium power solution, for applications such as spectroscopy of atoms, ions and molecules, laser cooling and interferometry. Designed in TOPTICA’s proprietary pro technology, it combines best performance and ease-of-use – at moderate initial and operating costs. The package comprises a solid laser head and a 19” control rack. It can be upgraded to a TA SHG pro, if an appropriate amplifier source is available.
