Page 9: Protection Features
Protection Features includes a number of features to protect you MOGL MGPA and your laser. Softstart A time delay (3 s) followed by linearly ramping the pump diode current (1 s/A max). Circuit shutdown Many areas of the circuitry are powered down when not in use. - Page 10 viii Key-operated The amplifier cannot be powered unless the key-operated STANDBY switch is in the position, to protect against unauthorised or accidental use. The key cannot be removed from the con- troller when it is in the clockwise ( ) position. Interlocks The main unit has an external interlock to allow the amplifier to be disabled via a remote switch.

Page 13: Introduction
1. Introduction is a modular compact fibre amplifier system MOGL MGPA based on Er and Yb doped active fibres. It uses an internal or exter- nal (depending on the model) seed laser and an amplification stage providing output power levels up to 2 W. The operating wavelength ranges include 1000 to 1100 nm for Yb active fibre and 1535 to 1610 nm for Er active fibre. -

Page 34: B5186 Headboard
Appendix C. Laser headboard C.1 B5186 headboard Headboard type B5186 provides high-speed active modulation of the diode current. It uses 500 MHz opamps and very low latency circuitry to reduce phase delay to around 12 ns. The B5186 allows for closed-loop bandwidth of about 4 MHz (without phase advance), which is helpful in achieving sub-Hz linewidth reduction by lock- ing to a high-finesse optical cavity. - Page 35 C.1 B5186 headboard C.1.1 input The B5186 input provides coupling to an active mod- ulation circuit. Note that connection to the input will reduce the diode current by about 2.5 mA, with zero input voltage. B5186 Input range ±2 0 V max Input coupling DC (direct) AC/DC (buffered)
