High power, widely tunable laser sources development

SGTC's laser lab is a high power laser development and research facility jointly setup by SGTC and Aerofluidics. Here, we develop state of the art, all solid state, high power, widely tunable laser sources for combustion study, chemical remote sensing, laser ablation analysis and machining.

Advantages of Our Technologies

All Solid-state technology --- no dyes, no solution pollutions
Widely tunable from deep UV 193nm to MWIR 5,000nm
High power from >100mJ in the UV to over 10mJ at 3,000nm

Image Rotated OPO w/ Intra-cavity UV harmonic

OPO pumped by a customized Nd:YAG capable of 2J IR output

Image rotated cavity OPO pumped at 532nm, intracvavity doubled/mixed

Fully computer controlled tuning and automatic adjustment

OPO and harmonic separator

High quality UV beam from the intracavity doubled OPO

SPECIALLY DESIGNED MOUNT FOR CRYSTAL USED IN HIGH POWER LASERS

Clear anodize that minimizes blast under intense laser power

The clear anodize is an essential design in laser devices that handles high laser power.

Compression spring design that provides restraint yet steady holding force on the crystal

This design is much superior to the setscrew design where the pressure of the set screw is very unpredictable and often results in crystal chipping and damage.

Stable mounting direction that minimize the movement of crystal in the sensitive direction

The clear anodize is an essential design in laser devices that handles high laser power.

Clear anodize that minimizes blast under intense laser power

The mount minimizes the crystal movement in the sensitive direction that the crystal will not move during cleaning with air duster or minor shock during transportation.
