A novel method of electron beam cooling is considered which can be used for linear colliders. The electron beam is cooled during collision with a focused powerful laser pulse. With reasonable laser parameters (laser flash energy about 10J) one can decrease transverse beam emittances by a factor of about 10 per stage. The ultimate transverse emittances are much below those achievable by other methods. Beam depolarization during cooling is about 5{percent}{endash}15{percent} for one stage. This method is especially useful for photon colliders and opens new possibilities for e{sup +}e{sup -} colliders and x-ray free-electron lasers based on high-energy linacs. {copyright} {ital 1997} {ital The American Physical Society}
