Notes

• Argon ion lasers having both of the following characteristics: 1. Operating at wavelengths between 400 and 515 nm; and 2. An average output power greater than 40 W;
• Lasers, laser amplifiers and oscillators as follows: N.B. See also in correspondence to 6A005
• Para-hydrogen Raman shifters designed to operate at 16 mm output wavelength and at a repetition rate greater than 250 Hz.
• Pulsed carbon monoxide lasers having all of the following characteristics: 1. Operating at wavelengths between 5 000 and 6 000 nm; 2. A repetition rate greater than 250 Hz; 3. An average output power greater than 200 W; and 4. Pulse width of less than 200 ns; Note: Item 3.A.2.j. does not control the higher power (typically 1 to 5 kW) industrial CO lasers used in applications such as cutting and welding, as these latter lasers are either continuous wave or are pulsed with a pulse width greater than 200 ns
• Tunable pulsed single-mode dye laser oscillators having all of the following characteristics: 1. Operating at wavelengths between 300 and 800 nm; 2. An average output power greater than 1 W; 3. A repetition rate greater than 1 kHz; and 4. Pulse width less than 100 ns;
• Tunable pulsed dye laser amplifiers and oscillators having all of the following characteristics: 1. Operating at wavelengths between 300 and 800 nm; 2. An average output power greater than 30 W; 3. A repetition rate greater than 1 kHz; and 4. Pulse width less than 100 ns; Note: Item 3.A.2.e. does not control single mode oscillators.
• Pulsed carbon dioxide lasers having all of the following characteristics: 1. Operating at wavelengths between 9 000 and 11 000 nm; 2. A repetition rate greater than 250 Hz; 3. An average output power greater than 500 W; and 4. Pulse width of less than 200 ns; Note: Item 3.A.2.g. does not control the higher power (typically 1 to 5 kW) industrial CO 2 lasers used in applications such as cutting and welding, as these latter lasers are either continuous wave or are pulsed with a pulse width greater than 200 ns.
• Neodymium-doped (other than glass) lasers with an output wavelength between 1 000 and 1 100 nm having either of the following: 1. Pulse-excited and Q-switched with a pulse duration equal to or greater than 1 ns, and having either of the following: a. A single-transverse mode output with an average output power greater than 40 W; or b. A multiple-transverse mode output with an average output power greater than 50 W; or 2. Incorporating frequency doubling to give an output wavelength between 500 and 550 nm with an average output power of greater than 40 W;
