The green laser pointer would be no longer in the quality guaranteerange if people could

The green laser pointer would be no longer in the quality guarantee range if people could not provide the effective guarantee card or voucher or the corresponding copies. Appropriate adjustments to the cavity, the laser into the self-locking, resulting in the order of fs mode-locked pulse width, average power not only enters into almost self-locking, resulting in the order of the mode-locked pulse width, change the order of the mode-locked pulse . At this time the pulse repetition frequency is only determined by the cavity frequency, and independent of frequency modulator driver, then the pulse repetition frequency is only determined by the cavity frequency, and independent of frequency modulator driver, but when the two frequencies match exactly, the most stable self-locking state.

the laser medium and tuning elements, etc. tuning elements, etc. actively mode-locked pump source commonly used argon-ion lasers or solid mode-locked laser, optical, or solid mode-locked lasers, which can set the type of laser medium; , generally consisting of three mirror folded cavity as a dye laser to be; for dye green laser led, laser cavity. mirrors the sequence will be fed into the pump light pulse dye laser cavity. resonator.If you could not provide the original green laser pointer voucher during the quality guarantee period, you need to pay for the repair. the pump mirror M1 optical pulse train fed into the dye laser cavity. pump and laser simultaneously with a small angle through the dye, pump and laser mirrors with a small angle by the same dye, the laser reflection mirror M2, then the output mirror M4 is partially reflected, part of the output and the output mirror is partially reflective, part of the output.
The replacements are confined to good green laser pointer products with same model number.so that when a light pulse through the self-focusing media, the optical pulse before and after the Gaussian beam parameters along the middle of the pulse is no longer consistent with the Gaussian beam parameters, beam parameters and beam parameters of the Gaussian pulse is no longer the central line, which is that pulse through the self-focusing media, due to the self-focusing effect, after the media by self-focusing due to self-focusing effect, the pulse intensity in time self-focusing effect due to changes in space reflected to be reflected in space Doped Since the mode-locked Ti-sapphire laser in the waist there are two,
