High Pressure Lasers

The High Pressure (HP) CO₂ laser range is based on the same technology as the Platinum CO₂ lasers. The major difference between these systems is that the former runs at gas pressures of 5–10Bar, while the latter runs at atmospheric pressures.

Versatility in the design and manufacturing processes allow all the systems below to be readily configured to meet the requirements of specific applications. Below are the specifications of the most common configurations obtained with 1:1:12 (CO₂:N₂:He) gas mixture. For more information on each laser use the highlighted link.

Product	Wavelength	Power	Repetition Rate	Pulse Energy*	Pulsewidth*
HP10	10.6μm	1.2W	10Hz	120mJ	80ns
HP20	10.6μm	2.4W	20Hz	120mJ	80ns
HP100	10.6μm	10W	100Hz	100mJ	80ns
HP300	10.6μm	30W	300Hz	100mJ	80ns

* These values are gas mixture dependent

The increase in pressure allows the CO₂ lasers to be continuously tuned from 9 to 11μm whereas the atmospheric lasers can only be tuned to specific vibrational lines between 9 and 11μm. The reason is to access wavelengths between vibrational lines, for isotope enrichment and photochemistry, and to increase the frequency bandwidth of the laser to amplify ultrafast pulses, for high energy physics.

The HP CO₂ lasers manufactured by SDILasers exhibit several unique features, such as:

High repetition rate operation beyond 250Hz
High energy electrical pulse compressor
Pressures up to 10Bar
Reliability
Closed loop gas operation with internal catalysts
Long component lifetime of >2 x10⁸ shots for all major components
Stable resonator design
