Abstract

A 2-J Ti:sapphire laser oscillator has been constructed by using an end-pumped configuration. The pump laser delivered as much as 10 J of energy (40–50 J cm−2) at 495 nm over a 4-μsec pulse length with no damage to the Ti:sapphire crystal. Ti:sapphire laser conversion efficiencies of 20% were obtained, and no parasitic oscillations were observed. A side-pumped Ti:sapphire oscillator delivered 0.7 J when pumped by 8 J of 495-nm radiation.

Ti:sapphire oscillator performance for both end-pump (solid curve) and side-pump (dashed curve) configurations. Output coupling fractions of 60 and 40% were used. Note that 97% of the pump energy is absorbed in the end-pump configuration and 85% is absorbed in the side-pump configuration.

Lasing and sidelight fluorescence temporal profiles for a side-pump configuration: a, lasing; b, sidelight fluorescence; c, sidelight fluorescence with a spoiled cavity. The pump energy was 8 J (8 J cm−2), and the lasing energy was 0.6 J.

Fig. 4
Fig. 4

Calculated and measured Ti:sapphire sidelight fluorescence signals for end-pump configuration (10 J/pulse, 40–50 J cm−2). The temporal behavior of the pump pulse is also shown. Note the agreement between calculations and measurements when single-pass ASE is included in the model.
