詳細信息

The Optilab PPL-1550-37-R is a fiber laser that produces picosecond pulses from electrical input pulses.

一、產品簡介:

The Optilab PPL-1550-37-R is a fiber laser that produces picosecond pulses from electrical input pulses. The system contains a pulsed seed laser as Master Ocillator (MO) and a Power Amplifier (PA). The PPL-1550-37-R is capable of producing < 200 ps optical pulse widths and corresponding repetition rates up to 100 MHz from the user’s electrical pulse input. The system contains two units with seed laser PPL-1550 and power amplifier EYDFA-37.
     The PPL-1550 consists of a stabalized DFB laser diode, centered at 1550 nm. The DFB laser operates under Continuous Wave (CW) mode, modulated by a high speed modulator rise time of less than 35 ps. EYDFA-37 is incorporated to amplify PPL-1550 output to 37 dBm. The PPL-1550-37-R features a standard remote control interface (RS-232) and an LCD display screen for easy user interface, accessible through a front panel adjustment knob. Contact Optilab for more information.
