LaseLock – Versatile Lock-Box
- Compact, stand-alone locking electronics
- Side-of-fringe and top-of-fringe stabilization
- Control bandwidth up to 1 MHz (optional 5 MHz)
- Two independent PID regulators
- High-voltage output (150 V)
The LaseLock is a universal lock-box for stabilizing lasers. It includes two PIDs and a lock-in regulator for side-of-fringe and top-of-fringe stabilization. It also features a scan generator, and with its HV output, it can drive Piezos directly. This stand-alone unit can also be used to stabilize third party lasers.
