Lasers
e2v manufactures a range of tubes used in laser excitation:
Copper Vapour Lasers
Copper vapour lasers utilising thyratron technology are used in machining applications. The important operating parameters are high frequency (>10 kHz) and high inverse voltages which place heavy demands on thyratron design. Other conditions are 20kV, 1kA, short 100ns pulse lengths, but rates of rise of current are high (>50 kA/µs) and the thyratron recovery time must be very fast.
CO² Laser
Low power CO² lasers are typically used for date coding and marking a variety of products. Typical operating conditions are 35 kV, 5 kA - 10 kA pulses of a few hundred nanoseconds length at 20 Hz or so. High power CO² lasers have replaced many traditional manufacturing methods such as punching, cutting, drilling and milling. They are also used for welding and a variety of materials processing, such as surface hardening.
Excimer Laser
Eximer lasers are used in a wide range of applications, including scientific investigations in the biological field, delicate medical treatments (e.g. eye surgery) and semiconductor processing. Operating conditions are generally 30 kV with up to 10 kA peak current pulses but only of a few hundred nanoseconds duration. Operating frequencies are modest at a few hundred Hz, but rate of rise of current is generally high (> 100 kA/µs). Jitter is sometimes an important parameter. Reliable operation is again paramount.
RF excited lasers
Gridded tubes are used to supply the RF power for RF excitation. The laser gas is excited by an RF field generated by the tube
