KLS System Operation Training

Overview

(KLS general operation, for everyone to come in to see how the whole system works.)

1. Overview: delay generator, pockels cell, pump lasers, power locking, LN2 system, chillers: normal operation (1-2h) - 5-8 people.

   Basic Knowledge

   (For all groups, since these itmes need to be done most frequently. One or two half-days training for 2 or 3 people each session. Following these classes and 1 or 2 beam times of practice, people should be able to operate on their own.)

2. Oscillator 1: quick alignment to get mode-lock (0.5-1h) - 3-5 people.
3. Amplifier 1: quick 4-mirror alignment (0.5-1h) - 3-5 people.
4. FROG and spectrometer: normal operation (2h) - 3-5 people.

   Advanced Techniques

   (For a small number of qualified people - post-docs and senior students, 2-3 people. Most difficult and time-consuming parts, especially class 5, but they need to be done quite frequently. Classes may take only two half-day sessions, but a long time of practice is needed to become an expert.)

5. Amplifier 2: full alignment of the optical path from the stretcher to amplifier and the amplifier cavity (4-6h) - 1-2 people.
6. Compressor: alignment to optimize 2nd and 3rd order dispersion (1-2h) - 3-5 people.
7. Hollow-core fiber and chirp mirrors: normal operation (1h) - 3-5 people.

   More Advanced Techniques

   (For a few senior people. They are difficult and rarely needed - once a year or less.)

8. Oscillator 2: full alignment of the cavity (3-4h) - 1-2 people.
9. Stretcher: alignment to eliminate spatial chirp (2h) - 1-2 people.

   Special Topics

   (Only for a couple of groups.)

10. Dazzler: operation of dazzler and amplifier alignment with dazzler (1h, assuming class 5 has been taken) - 1-2 people.
11. PCF and f-to-2f locking: alignment and normal operation (4h) - 1-2 people.
