3 3 INTRODUCTION Aim: To obtain, minimum beam waist in one plane (sagittal plane) σ 6μm (using green Laser oscillator, 532 nm) In present optical bench set up, we use IR (1064 nm) Laser oscillator We define term, Aspect ratio as ratio of mirror separation between adjacent plane and concave mirror to length of resonator R Sagittal = R/ cos α/2 Aspect ratio R Tangential = R cos α/2 α = tan 1 d L Present Laser Wire System in ATF damping ring is 2 mirror CW green laser wire system

22 22 MERITS 1. Four mirror resonator reduces the sensitivity to the misalignment of mirror compared to two mirror resonator, thus more stable. 2. At present, CW Laser Wire has been used to measure the small emittance beam. If we replace it to pulsed laser wire, more efficient laser-beam collision can be realized. 3. CW laser wire system takes more time in scanning of electron beam compare to Pulsed laser. 4. With green laser oscillator, beam waist less than 5 um can be obtained in one plane.
23 23 ANALYSIS Compact Cavity is very sensitive to mm accuracy. Scheme to obtain very small beam size requires proper mirror alignment scheme for fixing of mirrors. Green laser oscillator will give smaller beam size compare to IR oscillator Mode Locked fiber laser and high power optical cavity R & D Meeting
